This machine hosts the TRITON Unified Security Center (TRITON console), which includes: The infrastructure uniting all management components 2 Websense TRITON Enterprise Deployment and Installation Center A settings database, holding administrator account information and other data shared by all management components One or more management modules, used to access configuration, policy management, and reporting tools for a Websense security solution. Available modules include: TRITON - Web Security TRITON - Data Security TRITON - Email Security Additional components may also reside on the TRITON management server. Typically, the TRITON management server is a Windows Server 2008 R2 machine. If only the Web Security management module (TRITON - Web Security) is used, the TRITON management server can also be hosted on: Windows Server 2008 32-bit A V-Series appliance (recommended for evaluations only) Windows Server 2008 R2 (Standard and Enterprise) Windows Server 2008 (Standard and Enterprise) 32-bit V-Series Appliance Data Security Web Security Email Security Hardware requirements The following are minimum hardware recommendations for a TRITON management server. The requirements are different depending on whether Microsoft SQL Server 2008 R2 Express is installed on the management server or a remote installation of SQL Server is used. Deployment and Installation Center 3 Deployment and Installation Center With local reporting database TRITON console modules Minimum requirements TRITON - Web Security 4 CPU cores (2.5 GHz), 4 GB RAM, 100 GB Disk Space TRITON - Data Security 4 CPU cores (2.5 GHz), 8 GB RAM, 240 GB Disk Space TRITON - Web Security and Data Security 4 CPU cores (2.5 GHz), 8 GB RAM, 240 GB Disk Space TRITON - Email Security and Data Security 4 CPU cores (2.5 GHz), 8 GB RAM, 240 GB Disk Space All TRITON modules (Web Security, Data Security, and Email Security) 8 CPU cores (2.5 GHz), 16 GB RAM, 240 GB Disk Space Notes: Data Security allows for either local or remote installation of the forensics repository. If the repository is hosted remotely, deduct 90GB from the Data Security disk space requirements. It is strongly recommended you allocate more than the minimum listed disk space to allow for scaling with use. If you choose to install the Websense product on a drive other than the main Windows drive (typically C drive), then you must have at least 2GB free on the main Windows drive to accommodate for files to be extracted to this drive. With remote reporting database TRITON console modules Minimum requirements TRITON - Web Security 4 CPU cores (2.5 GHz), 4 GB RAM,7 GB Disk Space TRITON - Data Security 4 CPU cores (2.5 GHz), 8 GB RAM, 140 GB Disk Space TRITON - Web Security and Data Security 4 CPU cores (2.5 GHz), 8 GB RAM, 146 GB Disk Space TRITON - Email Security and Data Security 4 CPU cores (2.5 GHz), 8 GB RAM, 146 GB Disk Space TRITON - Web Security, Data Security, and Email Security 8 CPU cores (2.5 GHz), 16 GB RAM, 146 GB Disk Space Note: It is strongly recommended you have more disk space than the minimum specified above to allow for scaling with use. 4 Websense TRITON Enterprise Deployment and Installation Center If you choose to install the Websense product on a drive other than the main Windows drive (typically C drive), then you must have at least 2GB free on the main Windows drive to accommodate for files to be extracted to this drive. TRITON console browser support Use any of the following Web browsers to access the TRITON Unified Security Center. Browser Versions Microsoft Internet Explorer 8* and 9 Mozilla Firefox 4.x through 13.x Google Chrome 13 and later * For Internet Explorer 8 only, do not use compatibility mode. Virtualization systems All TRITON Unified Security Center components are supported on these virtualization systems: Hyper-V over Windows Server 2008 R2 VMware over Windows Server 2008 R2 Note that this support is for the TRITON console only. Other components (used for filtering, analysis, reporting, or enforcement) may have additional requirements that are not supported by these virtualization environments. Directory services for administrator authentication If you allow users to log on to the TRITON console using their network accounts, the following directory services can be used to authenticate administrator logons: Microsoft Active Directory Novell eDirectory Lotus Notes Oracle Directory Server Generic LDAP directories Reporting database requirements For all Websense security solutions, Microsoft SQL Server is used to host the reporting database. The TRITON Unified Installer can be used to install Microsoft SQL Server 2008 R2 Express on the TRITON management server machine. This configuration is best for evaluations and small deployments. Deployment and Installation Center 5 Deployment and Installation Center Only use the version of SQL Server 2008 R2 Express included in the Websense software installer. Larger organizations are advised to use a Standard or Enterprise version of Microsoft SQL Server. Note that these SQL Server versions cannot reside on the TRITON management server.

For more information, see the Websense knowledge article: “File System Performance Optimization.” Windows installation requirements: Set the partition to 1 NTFS Partition. For more information, see the Websense knowledge-base article: “File System Performance Optimization.” Regional Settings: should be set according to the primary location. If necessary, add supplemental language support and adjust the default language for non-Unicode programs. Configure the network connection to have a static IP address. The Data Security Management Server host name must not include an underscore sign. Internet Explorer does not support such URLs. Short Directory Names and Short File Names must be enabled. (See http:// support.microsoft.com/kb/121007.) Create a local administrator to be used as a service account. If your deployment includes more than one Data Security Server, use a domain account (preferred), or the use same local user name and password on each machine. Be sure to set the system time accurately on the TRITON management server.

There should be no pending updates, especially any requiring a restart of the system. In addition to the space required by the Websense installer itself, further disk space is required on the Windows installation drive (typically C) to accommodate temporary files extracted as part of the installation process. For information on minimum disk space requirements, see Hardware requirements, page 3. NET Framework version 2.0 or higher is required to run the Windows installer. If .NET 2.0 is not already installed, it is available from www.microsoft.com. Note Both .NET Framework 2.0 and 3.5 SP1 are required if you are installing SQL Server Express. Getting the Websense software installers The Websense Windows installer is used to install TRITON Unified Security Center; Web Security, Data Security, and Email Security components; and SQL Server 2008 R2 Express. There are also Linux installers for installing Web Security components and Content Gateway. The installers are also used to upgrade most prior-version components. 14 Websense TRITON Enterprise Deployment and Installation Center Download the installers from mywebsense.com. The Windows installer is named WebsenseTRITON77Setup.exe. Double-click it to start the installation process. If you have previously run the Websense installer on a machine, and you selected the Keep installation files option, go to Start > All Programs > Websense > Websense TRITON Setup to restart the installer without extracting all of the files a second time. Note that the files occupy approximately 2 GB of disk space. The Web Security Linux installer is WebsenseWeb77Setup_Lnx.tar.gz. The Content Gateway installer is WebsenseCG77_Lnx.tar.gz. Domain Admin privileges Websense components are typically distributed across multiple machines. Additionally, some components access network directory services or database servers. To install Websense components, it is a best practice to log in to the machine as a user with domain admin privileges. Otherwise, components may not be able to properly access remote components or services. Important If you plan to install SQL Server 2008 R2 Express and will use it to store and maintain Web Security data, you must log in as a domain user when installing it (i.e., log in to the machine as a domain user prior to running the Websense installer). Synchronizing clocks If you are distributing Websense components across different machines in your network, synchronize the clocks on all machines where a Websense component is installed. It is a good practice to point the machines to the same Network Time Protocol server. Note If you are installing components that will work with a Websense V-Series appliance, you must synchronize the machine’s system time to the appliance’s system time. Deployment and Installation Center 15 Deployment and Installation Center Antivirus Disable any antivirus on the machine prior to installing Websense components. Be sure to re-enable antivirus after installation. Certain Websense files should be excluded from antivirus scans to avoid performance issues; see Excluding Websense files from antivirus scans, page 724. No underscores in FQDN For best practices, do not install Websense components on a machine whose fullyqualified domain name (FQDN) contains an underscore. The use of an underscore character in an FQDN is not a supported Internet Engineering Task Force (IETF) standard, an official Internet standard, that Websense complies with. Note Further details of this limitation can be found in the IETF specifications RFC-952 and RFC-1123. TRITON Unified Security Center In addition to the general preparation actions (see All Websense security solutions, page 14), before installing the TRITON Unified Security Center, note the following: Do not install the TRITON Unified Security Center on a domain controller machine. If you want to run Microsoft SQL Server on the TRITON management server, use the Websense installer to install SQL Server 2008 R2 Express. If you are using a remote installation of SQL Server, you can use any of the supported versions (see System requirements for this version, page 2). SQL Server 2008 R2 Express The following third-party components are required to install Microsoft SQL Server 2008 R2 Express. Although the Websense installer will install these components automatically if they are not found, it is a best practice to install the components first, before running the Websense installer. .NET Framework 3.5 SP1 . Note Because the installer requires .NET 2.0, both .NET 2.0 and 3.5 SP1 are required if you are installing SQL Server Express. Windows Installer 4.5 16 Websense TRITON Enterprise Deployment and Installation Center Windows PowerShell 1.0 PowerShell is available from Microsoft (www.microsoft.com). If you will use SQL Server 2008 R2 Express to store and maintain Web Security data, you must log in to the machine as a domain user to run the Websense installer. Service Broker, which is installed as part of SQL Server 2008 R2 Express, must be able to authenticate itself against a domain. Logging in as a domain user when running the installer makes sure Service Broker is installed to run as the domain user. Web security In addition to the general preparation actions (see All Websense security solutions, page 14), see the following if you will be installing Web Filter, Web Security, Web Security Gateway, or Web Security Gateway Anywhere components. Filtering Service Internet access To download the Websense Master Database and enable filtering, each machine running Websense Filtering Service must be able to access the download servers at: download.websense.com ddsdom.websense.com ddsint.websense.com portal.websense.com my.websense.com Make sure that these addresses are permitted by all firewalls, proxy servers, routers, or host files that control the URLs that Filtering Service can access. Firewall Disable any firewall on the machine prior to installing Websense components. Be sure to disable it before starting the Websense installer and then re-enable it after installation. Open ports as required by the Websense components you have installed. Note The Websense installer adds two inbound rules to the public profile of Windows Firewall. Ports 9443 and 19448 are opened for TRITON Infrastructure. These ports must be open to allow browsers to connect to the TRITON Unified Security Center. Also, additional rules may be added to Windows Firewall when installing Websense Data Security components. See Websense TRITON Enterprise default ports, page 712, for more information about ports used by Websense components. Deployment and Installation Center 17 Deployment and Installation Center Computer Browser Service (Windows Server 2008) To install Websense software on a Windows Server 2008 machine, the Computer Browser Service must be running (note: on most machines you will find it disabled by default). Network Agent If you are installing Network Agent, ensure that the Network Agent machine is positioned to be able to monitor and respond to client Internet requests. In standalone installations (which do not include Content Gateway or a third-party integration product), if you install Network Agent on a machine that cannot monitor client requests, basic HTTP filtering and features such as protocol management and Bandwidth Optimizer cannot work properly. Important Do not install Network Agent on a machine running a firewall. Network Agent uses packet capturing that may conflict with the firewall software. The network interface card (NIC) that you designate for use by Network Agent during installation must support promiscuous mode. Promiscuous mode allows a NIC to listen to IP addresses other than its own. If the NIC supports promiscuous mode, it is set to that mode by the Websense installer during installation. Contact your network administrator or the manufacturer of your NIC to see if the card supports promiscuous mode. On Linux, do not choose a NIC without an IP address (stealth mode) for Network Agent communications. Note If you install Network Agent on a machine with multiple NICs, after installation you can configure Network Agent to use more than one NIC. See the “Network Configuration” topic in the TRITON - Web Security Help for more information. Network Agent using multiple NICs on Linux If Network Agent is installed on a Linux machine, using one network interface card (NIC) for blocking and another NIC for monitoring, make sure that either: The blocking NIC and monitoring NIC have IP addresses in different network segments (subnets). You delete the routing table entry for the monitoring NIC. If both the blocking and monitoring NIC on a Linux machine are assigned to the same subnet, the Linux operating system may attempt to send the block via the monitoring 18 Websense TRITON Enterprise Deployment and Installation Center NIC. If this happens, the requested page or protocol is not blocked, and the user is able to access the site. Installing on Linux Most Web Security components can be installed on Linux. If you are installing on Linux complete the instructions below. SELinux Before installing, if SELinux is enabled, disable it or set it to permissive. Linux firewall If Websense software is being installed on a Linux machine on which a firewall is active, shut down the firewall before running the installation. 1. Open a command prompt. 2. Enter service iptables status to determine if the firewall is running. 3. If the firewall is running, enter service iptables stop. 4. After installation, restart the firewall. In the firewall, be sure to open the ports used by Websense components installed on this machine. See Websense TRITON Enterprise default ports, page 712. Important Do not install Websense Network Agent on a machine running a firewall. Network Agent uses packet capturing that may conflict with the firewall software. See Network Agent. Hostname Before installing to a Linux machine, make sure the hosts file (by default, in /etc) contains a hostname entry for the machine, in addition to the loopback address. (Note: you can check whether a hostname has been specified in the hosts file by using the hostname -f command.) To configure hostname: 1. Set the hostname: hostname <host> Here, <host> is the name you are assigning this machine. 2. Also update the HOSTNAME entry in the /etc/sysconfig/network file: HOSTNAME=<host> 3. In the /etc/hosts file, specify the IP address to associate with the hostname. This should be static, and not served by DHCP. Do not delete the second line in the file, the one that begins with 127.0.0.1 (the IPv4 loopback address). And do not delete the third line in the file, the on that begins ::1 (the IPv6 loopback address). Deployment and Installation Center 19 Deployment and Installation Center <IP address> 127.0.0.1 ::1 <FQDN> localhost.localdomain localhost6.localdomain6 <host> localhost localhost6 Here, <FQDN> is the fully-qualified domain name of this machine (i.e., <host>.<subdomains>.<top-level domain>)—for example, myhost.example.com—and <host> is the name assigned to the machine. Important The hostname entry you create in the hosts file must be the first entry in the file. TCP/IP only Websense software supports only TCP/IP-based networks. If your network uses both TCP/IP- and non-IP-based network protocols, only users in the TCP/IP portion of the network are filtered. Data Security See below for information about preparing to install Data Security components. Do not install Data Security Server on a DC Do not install Data Security Server on a domain controller (DC) machine. Domain considerations The servers running the Data Security software can be set as part of a domain or as a separate workgroup. If you have multiple servers or want to perform run commands on file servers in response to discovery, we recommend you make the server or servers part of a domain. However, strict GPOs may interfere and affect system performance, and even cause the system to halt. Hence, when putting Data Security servers into a domain, it is advised to make them part of organizational units that don’t enforce strict GPOs. Also, certain real-time antivirus scanning can downgrade system efficiency, but that can be relieved by excluding some directories from that scanning (see Excluding Websense files from antivirus scans, page 724). Please contact Websense Technical Support for more information on enhancing performance. 20 Websense TRITON Enterprise Deployment and Installation Center Obtaining Microsoft SQL Server Deployment and Installation Center | Web, Data, and Email Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Data Security, v7.7.x Email Security Gateway and Gateway Anywhere, v7.7.x Prior to installing Websense components, Microsoft SQL Server must be installed and running on a machine in your network. See System requirements for this version, page 2, for supported versions of SQL Server. Note that full versions of Microsoft SQL Server are not included in your Websense subscription, and must be obtained separately. Refer to Microsoft documentation for installation and configuration instructions. If you do not have SQL Server, you can use the Websense installer to install SQL Server 2008 R2 Express, a free-of-charge, limited performance version of SQL Server 2008 R2. If you choose to use SQL Server 2008 R2 Express: Use the Websense installer to install it. Do not download and install it from any other source. This is the only Express edition of SQL Server you can use with Websense version 7.7.x solutions. SQL Server 2008 R2 Express can be installed either on the TRITON management server or on a separate machine. For smaller enterprises, if you want to run SQL Server on the TRITON management server, it is a best practice to use SQL Server 2008 R2 Express. For larger enterprises, however, it is a best practice to run the TRITON Unified Security Center and SQL Server on separate physical machines. Note It is a best practice to use full versions of SQL Server in production environments. SQL Server 2008 R2 Express is most appropriate for non-production or evaluation environments. See Administering Websense Databases for more information. To install SQL Server 2008 R2 Express on the TRITON management server, choose to do so during the installation of TRITON Infrastructure. See Creating a TRITON Management Server, page 180, for more information. Deployment and Installation Center 21 Deployment and Installation Center To install SQL Server 2008 Express R2 on any other machine run the Websense installer in custom installation mode and select SQL Server Express. See Installing SQL Server 2008 R2 Express (without TRITON Infrastructure), page 417. 22 Websense TRITON Enterprise 2 Web Security Deployment Recommendations Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Deploying Web Security core components, page 24 Understanding Web Security standalone and integrated modes, page 30 Extending your Web Security deployment, page 31 Additional reporting considerations, page 35 Web Security required external resources, page 41 Maximizing Web Security system performance, page 42 Deploying Web Security hybrid filtering components, page 46 Deploying transparent identification agents, page 48 Hardware recommendations for standalone Web Security deployments, page 51 Standalone deployment guidelines for Network Agent, page 53 Positioning Network Agent in the network, page 55 Deploying Remote Filtering Server and Client, page 62 Using the TRITON management server as policy source for filtering-only appliances, page 64 Deployment and Installation Center 23 Web Security Deployment Recommendations Deploying Web Security core components Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Core policy components, page 26 Core management components, page 28 Core reporting components, page 29 This section of the Deployment and Installation Center describes the core components required by all Websense Web Security solutions, and explains how they are typically distributed. For information about how a deployment can be extended beyond the core components, see Extending your Web Security deployment, page 31, and Deploying transparent identification agents, page 48. If you have a Web Security Gateway solution, also see Content Gateway Deployment, page 83. 24 Websense Web Security Solutions Web Security Deployment Recommendations Additional information for distributed enterprise deployments is available in Deploying Web Security for a distributed enterprise, page 65. Deployment and Installation Center 25 Web Security Deployment Recommendations Core policy components To ensure effective filtering, Websense Web Security core management components must be installed so that: All components can communicate with a central installation of Policy Broker. There can be only one Policy Broker instance per deployment. In software installations, Policy Broker can run on Windows or Linux. With Websense appliances, Policy Broker is present on the full policy source appliance only. 26 Websense Web Security Solutions Web Security Deployment Recommendations There is a central instance of Policy Server. In software installations, the central Policy Server instance runs on the Policy Broker machine. With Websense appliances, Policy Server is present on the full policy source appliance. Additional instances of Policy Server can be deployed on Windows or Linux machines, or on user identification and filtering appliances. Most components must be able to communicate with Policy Server on ports 55806 and 40000. (The exceptions are Remote Filtering Server and State Server.) At least one instance of Filtering Service communicates with the central Policy Server. Most components must be able to communicate with Policy Broker on port 55880. (The exceptions are all optional components: transparent identification agents, State Server, Multiplexer, Linking Service, and Directory Agent.) In software installations, Filtering Service can run on the same machine as Policy Broker and Policy Server. With Websense appliances, a Filtering Service instance is present on the full policy source appliance. Additional instances of Filtering Service can be deployed on Windows or Linux machines, or on either user identification and filtering (includes Policy Server) or filtering only (must point to a remote Policy Server) appliances. Filtering Service is configured to receive HTTP(S) requests from one of the following: Content Gateway (Websense Web Security Gateway or Gateway Anywhere deployments). Network Agent (Websense Web Filter or Web Security standalone deployments). An integrated third-party firewall, proxy server, or caching application (Websense Web Filter or Web Security integrated deployments). Deployment and Installation Center 27 Web Security Deployment Recommendations Core management components The TRITON Unified Security Center (TRITON console) is the centralized management console for Websense Web, data, and email security solutions. The TRITON console includes global administrator settings and appliance connection data, as well as 3 management modules: Web Security, Data Security, and Email Security. TRITON - Web Security is the console used to perform product configuration, policy management, and reporting tasks for Websense Web Security solutions. Install all TRITON Unified Security Center components on a single Windows server (sometimes called the TRITON management server). For evaluation and demonstration purposes, TRITON - Web Security is available on Websense appliances. As a best practice, use a separate, Windows-based TRITON management server for production environments. TRITON - Web Security must be able to communicate with: Policy Broker on port 55880 Policy Server on ports 40000, 55806, 55817, 55818, and 55824 Filtering Service on port 55807 Log Server on ports 55812 and 55805 User Service on port 55815 28 Websense Web Security Solutions Web Security Deployment Recommendations Core reporting components Web Security Log Server receives information about Internet activity from Filtering Service and processes it into the Log Database. Install Log Server on a dedicated Windows server. Because collecting and processing log records is resource-intensive, Log Server should typically not run on the same machine other resource-sensitive components, like the TRITON console or Filtering Service. The Log Database resides on a supported Microsoft SQL Server machine. Log Server does not run on Websense appliances. Do not run Log Server on the SQL Server machine. By default, Log Server communicates with SQL Server on the default ODBC port (1433). A custom port can be specified during installation. See Using a custom port to connect to the Log Database, page 35. The TRITON console machine must be able to communicate with Log Server and the Log Database. Deployment and Installation Center 29 Web Security Deployment Recommendations Understanding Web Security standalone and integrated modes Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Websense Web Filter and Web Security may either be installed as a standalone solution, or be integrated with a third-party proxy, cache, or firewall product (for example, Check Point Firewall-1 NGX, Cisco ASA, or Microsoft Forefront TMG). In a standalone deployment, Websense Network Agent monitors Internet activity from all users and forwards both HTTP(S) requests and requests made via other protocols to Websense Filtering Service to determine whether to permit or block the request. For information about using Network Agent to enable a standalone deployment, see Standalone deployment guidelines for Network Agent, page 53. In an integrated deployment, the third-party product (integration product) forwards HTTP(S) requests, and sometimes also FTP requests, to Websense Filtering Service to determine whether to permit or block the request. For information about integrating Web Filter or Web Security with a third-party product, see: Integrating Web Security with Check Point, page 445 Integrating Web Security with Cisco, page 481 Integrating Web Security with Citrix, page 513 Integrating Web Security using ICAP Service, page 557 Integrating Web Security with Microsoft Products, page 535 Installing Web Security for Universal Integrations, page 563 Websense Web Security Gateway and Gateway Anywhere solutions include Websense Content Gateway, a high-performance Web proxy that provides real-time threat analysis and Web site classification. With Web Security Gateway solutions, Content Gateway forwards HTTP(S) and FTP requests to Websense Filtering Service to determine whether to permit or block the request. For information about deploying Content Gateway with Web Security Gateway or Gateway Anywhere, see Content Gateway Deployment, page 83. 30 Websense Web Security Solutions Web Security Deployment Recommendations Extending your Web Security deployment Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Filtering Services per Policy Server, page 32 Network Agents per Filtering Service, page 33 Policy Server, Filtering Service, and State Server, page 33 Policy Server, Filtering Service, and Multiplexer, page 34 In large, high-traffic, or geographically distributed organizations, you can deploy multiple groups of policy components, each with its own Websense Policy Server instance, to: Provide load-balancing capabilities. Improve filtering responsiveness in locations far away from the central Web Security installation. Manage high amounts of traffic. All Policy Server instances connect to the same, central Policy Broker. Except in very rare circumstances, all Policy Server instances also connect to the same, central instance of TRITON - Web Security. Each Policy Server instance can support: Up to 10 Filtering Service instances (see Filtering Services per Policy Server, page 32) Each Filtering Service can support up to 4 Network Agent instances (see Network Agents per Filtering Service, page 33) 1 User Service 1 Usage Monitor 1 Web Security Log Server 1 State Server (see Policy Server, Filtering Service, and State Server, page 33) 1 Multiplexer (see Policy Server, Filtering Service, and Multiplexer, page 34) 1 Directory Agent (Websense Web Security Gateway Anywhere only; see Directory Agent, page 47) Deployment and Installation Center 31 Web Security Deployment Recommendations Filtering Services per Policy Server As a best practice, no more than 10 Filtering Service instances should be deployed per Policy Server. A Policy Server instance may be able to handle more, depending on the load. However, if the number of Filtering Service instances exceeds the Policy Server’s capacity, responses to Internet requests may be slowed. Multiple Filtering Service instances are useful to manage remote or isolated subnetworks. The appropriate number of Filtering Service instances for a Policy Server depends on: The number of users per Filtering Service The configuration of the Policy Server and Filtering Service machines The volume of Internet requests The quality of the network connection between the components If a ping command sent from one machine to another receives a response in fewer than 30 milliseconds (ms), the connection is considered high-quality. See Testing the Policy Server to Filtering Service connection, page 32. If Filtering Service and Policy Server become disconnected, all Internet requests are either blocked or permitted, as configured on the Settings > General > Account page TRITON - Web Security. For more information, see Configuring your account information in the TRITON - Web Security Help. Filtering Service machines running behind firewalls or running remotely (at a great topological distance, communicating through a series of routers) may need their own Policy Server instance. In a multiple Policy Server environment, a single Websense Policy Database holds the policy settings for all Policy Server instances. See the TRITON - Web Security Help for more information. Testing the Policy Server to Filtering Service connection Run a ping test to check the response time and connection between the Policy Server and Filtering Service machines. A response time of fewer than 30 milliseconds is recommended. 1. Open a command prompt (Windows) or terminal session (Linux) on the Policy Server machine. 2. Enter the following command: ping <IP address or hostname> Use the IP address or hostname of the Filtering Service machine. On Windows machines, the results resemble the following: C:\>ping 11.22.33.254 Pinging 11.22.33.254 with 32 bytes of data: Reply from 11.22.33.254: bytes=32 time=14ms TTL=63 Reply from 11.22.33.254: bytes=32 time=15ms TTL=63 32 Websense Web Security Solutions Web Security Deployment Recommendations Reply from 11.22.33.254: bytes=32 time=14ms TTL=63 Reply from 11.22.33.254: bytes=32 time=15ms TTL=63 Ping statistics for 11.22.33.254: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 14ms, Maximum = 15ms, Average = 14ms In a Linux environment, the results look like this: [root@localhost root]# ping 11.22.33.254 PING 11.22.33.254 (11.22.33.254) 56(84) bytes of data. 64 64 64 64 bytes bytes bytes bytes from from from from 11.22.33.254: 11.22.33.254: 11.22.33.254: 11.22.33.254: icmp_seq=2 icmp_seq=3 icmp_seq=4 icmp_seq=1 ttl=127 ttl=127 ttl=127 ttl=127 time=0.417 time=0.465 time=0.447 time=0.854 ms ms ms ms Ensure that Maximum round trip time or the value of time=x.xxx ms is fewer than 30 ms. If the time is greater than 30 ms, move one of the components to a different network location and run the ping test again. If the result is still greater than 30 ms, locate and eliminate the source of the slow response. Network Agents per Filtering Service As a best practice, no more than 4 Network Agent instances should be deployed per Filtering Service. One Filtering Service instance may be able to handle more than 4 Network Agents, depending on the number of Internet requests, but if Filtering Service or Network Agent capacities are exceeded, filtering and logging inconsistencies may occur. Network Agent can typically monitor 50 Mbps of traffic per second, or about 800 requests per second. The number of users that Network Agent can monitor depends on the volume of Internet requests from each user, the configuration of the network, and the location of Network Agent in relation to the computers it is assigned to monitor. Network Agent functions best when it is close to those computers. Network Agent communicates with Filtering Service on port 15868. Policy Server, Filtering Service, and State Server If your deployment includes multiple instances of Filtering Service that might handle a request from the same user, an optional component, Websense State Server, can be installed to enable proper application of time-based filtering actions. For example, users can be granted quota time, which gives them access to sites in selected categories for a limited (configurable) time period. When State Server is installed, its associated Filtering Service instances share timing information, so users receive the correct allotment of access to time-restricted categories. State Server is typically installed on a Policy Server machine, and only one State Server instance is required per logical deployment. Deployment and Installation Center 33 Web Security Deployment Recommendations A logical deployment is any group of Policy Server and Filtering Service instances that might handle requests from the same set of users. State Server can be enabled via the command-line interface on full policy source or user identification and filtering appliances. All Filtering Service instances that communicate with the same State Server instance must share the same time zone, and the time on all machines must be in synch. State Server communicates with Filtering Service on port 55828. Each Filtering Service instance can communicate with only one State Server. All Filtering Service instances associated with the same Policy Server must communicate with the same State Server. Multiple Policy Server instances can share a single State Server. In a geographically dispersed organization, where each location has its own Policy Server and Filtering Service instances, deploy one State Server instance (on the Policy Server machine or V-Series appliance) at each location. In an organization where all requests are filtered through a central location, only one State Server instance is needed. Policy Server, Filtering Service, and Multiplexer Websense Web Security solutions can be configured to pass logging data (the same information processed by Log Server) to a third-party Security and Information and Event Management (SIEM) product. When SIEM integration is enabled, Websense Multiplexer collects log data from Filtering Service and passes it to both Log Server and the integrated SIEM product. (When SIEM integration is disabled, Filtering Service sends log data directly to Log Server, with no intermediary.) Multiplexer is typically installed on the Policy Server machine. When Policy Server resides on a V-Series Appliance, always enable Multiplexer on the appliance. Do not attempt to connect an off-appliance Multiplexer instance to the on-appliance Policy Server. With software (non-appliance) installations of Policy Server, it does not matter whether Multiplexer is on the same machine or a different machine. Install one Muliplexer per Policy Server. Multiplexer can be enabled via the command-line utility on full policy source or user identification and filtering appliances. Multiplexer communicates with the following components: Policy Server on ports 40000, 55806, and 56010 Filtering Service on port 55805 (inbound) Log Server on port 55805 (outbound) SIEM integration (port varies; 514 for TCP and 515 for UDP) 34 Websense Web Security Solutions Web Security Deployment Recommendations Additional reporting considerations Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Using a custom port to connect to the Log Database, page 35 Using SSL to connect to the Log Database, page 35 Using BCP for log record insertion with SQL Server 2008, page 36 Configuring distributed logging, page 37 When you install Web Security reporting components, you can configure how those components communicate with the SQL Server database (Log Database). Port and encryption settings selected during installation can be changed after installation, if needed. In addition, if you are planning to deploy reporting components for a large or geographically distributed organization, and need to use a single, centralized database for reporting, see Configuring distributed logging, page 37, for configuration options. Using a custom port to connect to the Log Database During TRITON Infrastructure and Websense Log Server installation, you can specify which port to use for Microsoft SQL Server communication. By default, the standard ODBC port (1433) is used. If you want to use another port, keep in mind that SQL Server typically assigns: A fixed port to the default instance (MSSQLSERVER) A dynamic port to each named instance Use the SQL Server Configuration Manager to configure the port used by each SQL Server instance. See your Microsoft documentation for assistance. Using SSL to connect to the Log Database During TRITON Infrastructure and Websense Log Server installation, you are given the option to connect to Microsoft SQL Server using an SSL-encrypted connection. In determining whether to configure reporting and management components to use SSL encryption for Log Database communication, keep in mind that: Deployment and Installation Center 35 Web Security Deployment Recommendations BCP (bulk copy program) cannot be used to add records to the Log Database. Log Database connections are slower, which may affect reporting performance. If you are running TRITON - Web Security on a V-Series appliance (typically done only for evaluations), the connection from the management console to the database cannot be encrypted. If SSL is required, no data can be displayed in the Web Security Dashboard or other reporting tools. Before enabling SSL encryption during Websense software installation, configure Microsoft SQL Server encryption settings. 1. Launch SQL Server Configuration Manager (for example, Start > All Programs > Microsoft SQL Server 2008 > Configuration Tools > SQL Server Configuration Manager). 2. Right-click the SQL Native Client x.x Configuration entry used in your SQL Server installation, then select Properties. Two parameters are listed: Force Protocol Encryption: The default setting (No) means that encrypted connections are accepted but not required. This setting is typically best for use with Websense security solutions. If this is set to yes, only encrypted connections are accepted. Trust Server Certificate: The default setting (No) means that only certificates issued by a Certificate Authority (CA) are accepted for encrypting connections to the database. This requires that a CA-signed certificate be deployed to the SQL Server, Log Server, and TRITON management server machines before Websense components can use a secure connection to connect to the database. When this parameter is set to Yes, self-signed SSL certificates may be used to encrypt the connection to the database. In this case, the certificate is generated by the SQL Server machine and shared by all components needing to connect to the database. If you enable SSL encryption during installation, Force Protocol Encryption is set to Yes, and Trust Server Certificate is set to No, CA-signed certificates must be installed on the TRITON management server and Log Server machines before the component installation will succeed. Using BCP for log record insertion with SQL Server 2008 The Web Security Log Database can use either of 2 methods to insert log records into the Log Database (reporting database): ODBC (Open Database Connectivity inserts records into the database individually, using a database driver to manage data between Log Server and Log Database. 36 Websense Web Security Solutions Web Security Deployment Recommendations BCP (Bulk Copy Program) inserts records into the Log Database in groups called batches. This option is recommended because it offers better efficiency than ODBC insertion. Before you can use BCP for log record insertion with SQL Server 2008, 2 Microsoft component must be installed on the Log Server machine: Microsoft SQL Server 2008 Native Client is installed by the TRITON Unified Installer, when you install Web Security Log Server on the machine. Microsoft SQL Server 2008 Command Line Utilities are available as a free download from Microsoft: http://www.microsoft.com/en-us/download/details.aspx?id=16177 After you install the SQL Server 2008 Command Line Utilities, perform the following configuration steps to ensure that Log Server can access the BCP utility: 1. Locate the bcp.exe file installed with the SQL Server 2008 Command Line Utilities and make a note of the path to the file. The default location is: C:\Program Files\Microsoft SQL Server\100\Tools\Binn\bcp.exe 2. Navigate to the Websense bin directory (C:\Program Files or Program Files (x86)\Websense\Web Security\bin\) and open LogServer.ini in a text editor. 3. Locate the BCPExePath parameter, and set its value to the path noted in step 1. For example: BCPExePath=C:\Program Files\Microsoft SQL Server\100\Tools\Binn\bcp.exe 4. Save and close the LogServer.ini file. 5. Use the Windows Services dialog box (Start > Administrative Tools > Services) to restart the Websense Log Server service. 6. Use the Settings > Reporting > Log Server page in TRITON - Web Security to configure Log Server to use BCP for log record insertion. Configuring distributed logging If you have a large or distributed environment that requires multiple Log Server instances, you can configure each Log Server to record data to a separate Log Database. If you do not need a central repository of reporting data that can be used to generate organization-wide reports, this may be the most efficient deployment option. If you, however, you need a single Log Database in order to store all reporting data in a central location, you have 2 options: Configure all Log Server instances to independently record their data in the same Log Database. Configure distributed Log Server instances to pass their data to a central Log Server, which then records all log records from all instances into the Log Database. Deployment and Installation Center 37 Web Security Deployment Recommendations The first option does not require special configuration steps. You need only ensure that each Log Server instance points to the same database (both database engine IP address or hostname and database instance name). The second option requires more planning and configuration detail, as outlined in the sections that follow. Note that centralized log processing is not as fast as local logging. Expect a delay of 4 or 5 minutes before the files from remote Log Servers appear in the cache processing directory on the central Log Server. Part 1: Prepare for centralized logging 1. Identify or create a domain user account to use for running each Log Server service. For example: mydomain\WebsenseLogServer This ensures that permissions are consistent for all instances, and facilitates communication between distributed Log Server instances and the central instance. 2. Identify which Log Server instance will serve as the central Log Server and note its hostname or IP address. All remote Log Server instances must be able to communicate with the central Log Server machine. 3. Create a shared folder on the central Log Server machine for all Log Server instances to access: a. Create the folder. For example: C:\Program Files (x86)\Websense\Web Security\bin\logscache\ b. Right-click the new folder and select Properties. On the Sharing tab, select Share this folder and provide the information requested. Optionally, also restrict access to the folder to the domain user account assigned to all Log Server instances. The shared folder is available within the network via its UNC file path (\\<host_name>\<folder_name>). For example: \\logserver01\logscache 4. On the remote Log Server machines, create a mapped drive for the cache folder created in step 3: a. Log on to each Log Server machine as the domain user assigned to all Log Server instances. b. Open Windows Explorer and go to Tools > Map Network Drive. c. Select a drive letter for the mapped drive, browse to the shared folder created in step 3, and then click Finish. d. Make sure that you can copy a small text file from the remote Log Server machine to the shared drive. 38 Websense Web Security Solutions Web Security Deployment Recommendations Part 2: Configure the central Log Server 1. Go to the central Log Server machine and use the Windows Services dialog box (Start > Administrative Tools > Services) to stop Websense Log Server service. 2. Navigate to the Websense bin directory (C:\Program Files or Program Files (x86)\Websense\Web Security\bin, by default) and open the LogServer.ini file in a text editor. 3. Search for the phrase “Centralized LogServer,” then make the following changes: [CacheFileWatcher] Active=true TimeInterval=180 FilePath=<path_to_shared_cache_folder> Set the Active parameter to true to configure the central Log Server to process cache files from remote Log Server instances. Optionally, edit the TimeInterval value to determine how frequently (in seconds) the central Log Server checks the cache directory for new files to process. Set the FilePath parameter to the shared directory you created in Part 1 of this procedure (in the example above, the value is C:\Program Files (x86)\Websense\Web Security\bin\logscache\). 4. Next, search for [Visits] section of the file to change the UsingVisits parameter to false. (This can also be configured via the Settings > Reporting > Log Server page in TRITON - Web Security.) The section looks like this: [Visits] VisitTime=10 UsingVisits=false VisitSortTimeDelay=30 This ensures that visits processing (if enabled) is performed only once, by the remote Log Server instances. Note When centralized logging is used, log record consolidation is automatically disabled on remote Log Server instances (regardless of the setting in LogServer.ini or TRITON Web Security). To use log record consolidation, enable it for the central Log Server. 5. Save and close the file. 6. To configure this Log Server instance to run as the domain user created in Part 1 of this procedure: a. In the Windows Services dialog box, right-click Websense Log Server and select Properties. b. Select the Log On tab, then, under “Log on as,” click This account. c. Browse to the domain user created for this purpose, then enter and confirm the account password. Deployment and Installation Center 39 Web Security Deployment Recommendations d. When you are finished, click OK to return to the main Services window. 7. To start Log Server, right-click Websense Log Server again, then select Start. Part 3: Configure remote Log Server instances 1. Go to a remote Log Server machine and use the Windows Services dialog box to stop the Websense Log Server service. 2. Navigate to the Websense bin directory, then open the LogServer.ini file for that instance in a text editor. 3. Search for the phrase “Remote LogServer” and make the following changes: [LogFile] MoveCacheFile=TRUE MoveCacheFilePath=C:\Program Files\Websense\bin\CacheProcessing ProcessCacheFile=FALSE [UserGroups] ProcessGroups=FALSE ProcessUserFullName=FALSE ;Distributed Logging Remote LogServer [CacheLogging] Active=true TimeInterval=180 MinFileSize=1048576 MaxFileSize=5242880 CacheFileProcessingPath=C:\Program Files\Websense\bin\CacheProcessing CacheFileOutputPath=<UNC_path_to_mapped_drive> Set the Active parameter to true to configure the remote Log Server to place cache files in the “CacheFileProcessingPath” directory and forward them to the central Log Server. Optionally, change the TimeInterval value to determine how often (in seconds) the remote Log Server closes the current cache file and creates a new one. You can also edit the MinFileSize and MaxFileSize (in bytes) for each cache file. The default minimum is 1 MB; the default maximum is 5 MB. Set CacheFileProcessingPath to a local directory on the remote Log Server machine. Cache files are created on the local machine before being sent to the mapped drive on for processing by the central Log Server. Set CacheFileOutputPath to the UNC file path of the shared folder on the central Log Server machine. 4. If you want to record visits (rather than hits), and have turned off visits processing for the central Log Server service, make sure visits are enabled in the [Visits] section of the INI file for the remote Log Server instance. [Visits] VisitTime=10 40 Websense Web Security Solutions Web Security Deployment Recommendations UsingVisits=true VisitSortTimeDelay=30 Note When centralized logging is used, log record consolidation is automatically disabled on remote Log Server instances (regardless of the setting in LogServer.ini or TRITON Web Security). To use log record consolidation, enable it for the central Log Server. 5. Save and close the file. 6. To configure this Log Server instance to run as the domain user created in Part 1 of this procedure: a. In the Windows Services dialog box, right-click Websense Log Server and select Properties. b. Select the Log On tab, then, under “Log on as,” click This account. c. Browse to the domain user created for this purpose, then enter and confirm the account password. d. When you are finished, click OK to return to the main Services window. 7. To start Log Server, right-click Websense Log Server again, then select Start. Repeat the process for each remote Log Server machine. Web Security required external resources Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Websense software relies on the following external resources and network characteristics to function properly in your network. TCP/IP Websense software provides filtering in TCP/IP-based networks only. DNS server A DNS server is used to resolve requested URLs to an IP address. Network Agent, Content Gateway, or your third-party integration product requires efficient DNS performance. DNS servers should be fast enough to support Websense filtering without becoming overloaded. Directory services Deployment and Installation Center 41 Web Security Deployment Recommendations If Websense software is configured to apply user- and group-based policies, User Service queries the directory service for user information. Although these users and group relationships are cached by Websense software, directory service machines must have the resources to respond rapidly if Websense software requests user information. See System requirements for this version, page 2, for supported directory services. For information on configuring Websense software to communicate with a supported directory service, see the TRITON - Web Security Help. Websense software does not need to run on the same operating system as the directory service. Network efficiency The ability to connect to resources such as the DNS server and directory services is critical to Websense software. Network latency must be minimized if Filtering Service is to perform efficiently. Excessive delays under high load circumstances can impact the performance of Filtering Service and may cause lapses in filtering. Microsoft SQL Server A supported version of Microsoft SQL Server is required to host the Log Database, which stores reporting data for Websense Web Security solutions. See System requirements for this version, page 2, for supported SQL Server versions. SQL Server Standard or Enterprise works best for larger networks, or networks with a high volume of Internet activity, because of its capacity for storing large amounts of data over longer periods of time (several weeks or months). SQL Server Express, a free, limited-performance database engine, is bestsuited to smaller networks, organizations with a low volume of Internet activity, or organizations planning to generate reports on only short periods of time (for example, daily or weekly archived reports, rather than historical reports over longer time periods). Maximizing Web Security system performance Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, and Web Security Gateway (Anywhere), v7.7.x 42 Websense Web Security Solutions In this topic Network Agent, page 43 HTTP request logging, page 43 Microsoft SQL Server (Log Database), page 43 Log Database sizing considerations, page 44 Web Security Deployment Recommendations Adjust Websense components to improve filtering and logging response time, system throughput, and CPU performance. Network Agent As the number of users grows, or if Network Agent does not block Internet requests as expected, place Network Agent on a different machine from Filtering Service and Policy Server. You can also deploy additional Network Agent instances and divide network monitoring between them. If Websense software is running in a high-load environment, or with a high capacity Internet connection, you can increase throughput and implement load balancing by installing multiple Network Agent instances. Install each agent on a different machine, and configure each agent to monitor a different portion of the network. Network Agent must have bidirectional visibility into the network segment it monitors. If multiple Network Agents are installed, each agent must monitor a different network segment (IP address range). If a Network Agent machine connects to a switch, the monitor NIC must plug into a port that mirrors, monitors, or spans the traffic of all other ports. HTTP request logging You can use Network Agent or an integration product to track HTTP requests and pass the information to Websense software, which uses the data to filter and log requests. Network Agent and some integration products also track bandwidth activity (bytes sent and received), and the duration of each permitted Internet request. This data is also passed to Websense software for logging. When both Network Agent and the integration product provide logging data, the amount of processor time required by Filtering Service increases. If you are using both Network Agent and an integration product, you can avoid extra processing by configuring Websense software to use Network Agent to log HTTP requests (enhanced logging). When this feature is enabled, Websense software does not log HTTP request data sent by the integration product. Only the log data provided by Network Agent is recorded. Consult the TRITON - Web Security Help for configuration instructions. Microsoft SQL Server (Log Database) Under high load, Microsoft SQL Server operations are resource intensive, and can be a performance bottleneck for Websense software reporting. For best results: Do not install Web Security Log Server on the database engine machine. Deployment and Installation Center 43 Web Security Deployment Recommendations Provide adequate disk space to accommodate the growth of the Log Database. You can monitor growth and sizing information on the Settings > Reporting > Log Database page in TRITON - Web Security. Use a disk array controller with multiple drives to increase I/O bandwidth. Increase the RAM on the Microsoft SQL Server machine to reduce timeconsuming disk I/O operations. SQL Server clustering is supported for failover or high availability. Consult your Microsoft documentation for detailed information about optimizing Microsoft SQL Server performance. Log Database sizing considerations Log Database disk space requirements vary, based on: Network size Volume of Internet activity How long data must be available for use in reporting Logging settings It is important to host the database engine and Log Database on hardware that matches or exceeds the requirements for expected load and for historical data retention. Depending on the volume of Internet traffic in your network, and how much data your organization is required to store (based on organizational policy or compliance regulations, for example), the Log Database can become very large. To help determine an effective logging and reporting strategy for your organization, consider: When is the network traffic busiest? Schedule resource intensive database and reporting jobs at lower-volume times to improve logging and reporting performance during peak periods. See the TRITON - Web Security Help for information about scheduling database jobs, investigative reports, and presentation reports. How long should log data be kept to support historical reporting? Automatically delete partitions and trend data (stored in the catalog database) after they reach this age to reduce the amount of disk space required for the Log Database. See the TRITON - Web Security Help for information about managing Log Database partitions. How much detail is really needed in reports? To decrease Log Database size, consider: logging visits instead of hits (see Logging visits (default) vs. logging hits, page 45) disabling full URL logging (see Logging full URLs, page 45) 44 Websense Web Security Solutions Web Security Deployment Recommendations enabling consolidation (see Consolidation, page 45) only logging non-HTTP protocol traffic for selected protocols (see Protocol logging, page 46) only logging HTTP and HTTPS traffic in selected categories (see Selective category logging, page 46) All of these logging settings can be customized in TRITON - Web Security. Tune your logging settings to achieve the appropriate balance of size savings and report detail for your organization. Logging visits (default) vs. logging hits When you log visits, one log record is created for each Web page requested by a user, rather than each separate file included in the Web page request. This creates a smaller database and allows faster reporting. When you log hits, a separate log record is generated for each HTTP request to display any element of a Web page, including graphics and ads. This type of logging results in a larger and more detailed database than the logging visits option. Logging full URLs Enabling full URL logging creates a larger database than with logging hits, and also provides the most detailed reports. Log records include the domain name and the full path to specific pages requested. Use this option if you want reports of real-time scanning activity. If the Log Database is growing too quickly, you can turn off full logging to decrease the size of each entry and slow growth. Consolidation Consolidation helps to reduce the size of the database by combining Internet requests that share the same value for all of the following elements, within a certain interval of time (1 minute, by default): Domain name (for example: www.websense.com) Category Keyword Action (for example: Category Blocked) User For example, the user visits www.cnn.com and receives multiple pop-ups during the session. The visit is logged as a record. If consolidation is turned off (the default), and the user returns to the site later, a second visit is logged. If consolidation is turned on, additional visits to the site within a specified period are logged as a single record, with a hits (i.e., visits) count indicating the number of times the site was visited in that period. Deployment and Installation Center 45 Web Security Deployment Recommendations Protocol logging If your deployment includes Network Agent, you have the option to log non-HTTP protocol traffic (for example, instant messaging or streaming media traffic) in addition to HTTP and HTTPS traffic. The more protocols you choose to log, the greater the impact on the size of the Log Database. You can specify whether or not to log a specific protocol in each protocol filter that you create. Selective category logging By default, requests for URLs in all categories are logged. If your organization does not want to report on Internet requests for some categories, you can disable logging for those categories to help reduce Log Database size. Deploying Web Security hybrid filtering components Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Security Gateway Anywhere, v7.7.x In this topic Sync Service, page 46 Directory Agent, page 47 Websense Web Security Gateway Anywhere offers the ability to combine on-premises and hybrid (in-the-cloud or security-as-a-service) Web security solutions to manage Internet activity for your organization. Two on-premises components are used to hybrid Web security functionality: Websense Sync Service Websense Directory Agent Sync Service Websense Sync Service is required to send policy updates and user and group information from the on-premises deployment to the hybrid (cloud-based) service. Sync Service also retrieves reporting data from the hybrid service and passes it to Log Server so that it can be used in reports. There can be only one Sync Service instance in your deployment. Sync Service can be installed on the Log Server machine. If you have a distributed logging deployment (multiple Log Server instances pointing to a central Log Server), configure Sync Service to communicate with the central Log Server. 46 Websense Web Security Solutions Web Security Deployment Recommendations Sync Service must be able to communicate with: The hybrid service on port 443 Log Server on port 55805 (outbound) Directory Agent on port 55832 (inbound) TRITON - Web Security on port 55832 (inbound) Policy Broker on port 55880 (outbound) Policy Server on port 55830 (inbound) and ports 55806 and 40000 (outbound) Directory Agent Websense Directory Agent is required to enable user, group, and domain (OU) based filtering through the hybrid service. Directory Agent collects user, group, and OU information from a supported directory service and passes it to Sync Service in LDIF format. Sync Service then forwards the information to the hybrid service. Typically, only one Directory Agent instance is required in a deployment. Directory Agent can be installed on the same machine as other Websense components, including Sync Service and User Service. With Websense appliances, Directory Agent is installed on the full policy source or user directory and filtering appliance. When Directory Agent is installed, it must connect to a Policy Server instance that has an associated User Service instance. Directory Agent must communicate with the same directory service as User Service. If you have multiple User Service instances connected to different directory services, you can also have multiple Directory Agent instances, each associated with a different Policy Server. All Directory Agent instances must connect to a single Sync Service. (A deployment can have only one Sync Service instance.) Use TRITON - Web Security to configure the Sync Service connection manually for all supplemental Directory Agent instances. See “Directory Agent and User Service” in the TRITON - Web Security Help for configuration steps. Directory Agent must be able to communicate with: Your supported LDAP-based directory service (Windows Active Directory in Native Mode, Oracle Directory Server, or Novell eDirectory) If your organization uses Windows Active Directory in mixed mode, user and group data cannot be collected and sent to the hybrid service. Websense Sync Service on port 55832 Policy Server on ports 55806 and 40000 Deployment and Installation Center 47 Web Security Deployment Recommendations Once configured, Directory Agent collects user and group data from your directory service and sends it to Sync Service in LDIF format. At scheduled intervals, Sync Service sends the user and group information collected by Directory Agent to the hybrid service. Sync Service compresses large files before sending them. Deploying transparent identification agents Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: In this topic Web Filter, Web Security, and Web Security Gateway (Anywhere), v7.7.x Combining transparent identification agents, page 49 Use Websense transparent identification agents to identify users without prompting them for a user name and password in: Standalone Web Security deployments Integrated deployments in which the integration product does not send user information to Filtering Service There are 4 transparent identification agents: DC Agent is used with a Windows Active Directory. The agent: Works by identifying domain controllers in the network, and then querying those domain controllers for user logon sessions Can also be configured to poll client machines to verify logon status Runs on a Windows server and can be installed in any domain in the network Note Some DC Agent features require local and domain administrator privileges. Communicates with Filtering Service on port 30600 Logon Agent identifies users as they log on to Windows domains. The agent: May use NetBIOS port 139 for automatic domain detection. If NetBIOS port 139 is blocked in your network, deploy a DC Agent instance for each virtually or physically remote domain. Runs on a Linux or Windows server Requires a Windows-only client application (the Logon Application, or LogonApp.exe) to be run on client machines Communicates with Filtering Service on port 30602 eDirectory Agent is used with Novell eDirectory. The agent: 48 Websense Web Security Solutions Web Security Deployment Recommendations Runs on a Linux or Windows server Uses Novell eDirectory authentication to map users to IP addresses Communicates with Filtering Service on port 30700 RADIUS Agent can be used in conjunction with either Windows- or LDAP-based directory services. The agent: Runs on a Linux or Windows server Works with a RADIUS server and client to identify users logging on from remote locations Communicates with Filtering Service on port 30800 In deployments that cover multiple locations, you can install an agent instance in multiple domains. For example: One DC Agent instance can handle multiple trusted domains. Add additional instances based on: The load placed on DC Agent Whether a DC Agent instance can see all the domains on the network, including remote offices Load results from the number of user logon requests. With a large number of users (10,000+ users, 30+ domains), having multiple DC Agent instances allows for faster identification of users. If multiple Filtering Services are installed, each Filtering Service instance must be able to communicate with all DC Agent instances. One Logon Agent is required for each Filtering Service instance. One eDirectory Agent is required for each eDirectory Server. One RADIUS Agent instance is required for each RADIUS server. It is a best practice to install and run RADIUS Agent and the RADIUS server on separate machines. (The agent and server cannot have the same IP address, and must use different ports.) In some environments, a combination of transparent identification agents may be appropriate within the same network, or on the same machine. See Combining transparent identification agents, page 49. See Installing Web Security components, page 392, for transparent identification agent installation instructions. See the TRITON - Web Security Help for configuration information. Combining transparent identification agents Websense software can work with multiple transparent identification agents. If your environment requires multiple agents, it is best to install them on separate machines. eDirectory or RADIUS Agent can be installed on the same machine as Filtering Service, or on a separate server on the same network. Deployment and Installation Center 49 Web Security Deployment Recommendations Do not run eDirectory Agent and DC Agent in the same deployment. The following table lists supported combinations of transparent identification agents. Combination Same machine? Same network? Configuration required Multiple DC Agents No Yes Ensure that all instances of DC Agent can communicate with Filtering Service, and that the individual DC Agents are not monitoring the same domain controllers. Multiple RADIUS Agents No Yes Configure each agent to communicate with Filtering Service. Multiple instances of the RADIUS Agent cannot be installed on the same machine. Multiple eDirectory Agents No Yes Configure each instance to communicate with Filtering Service. Multiple Logon Agents No Yes Configure each instance to communicate with Filtering Service. DC Agent + RADIUS Agent Yes Yes Each agent must use a unique port number to communicate with Filtering Service. By default, DC Agent uses port 30600; RADIUS Agent uses port 30800. DC Agent + eDirectory Agent No No Communication with both a Windows directory service and Novel eDirectory is not supported in the same deployment. However, both agents can be installed, with only one agent active. DC Agent + Logon Agent Yes Yes Configure each agent to use a unique port to communicate with Filtering Service. By default, DC Agent uses port 30600; Logon Agent uses port 30602. RADIUS Agent + Logon Agent Yes Yes Configure all agents to communicate with Filtering Service. eDirectory Agent + Logon Agent No No Communication with both Novell eDirectory and a Windows- or LDAP-based directory service in the same deployment is not supported. However, both agents can be installed, with only one agent active. 50 Websense Web Security Solutions Web Security Deployment Recommendations Combination Same machine? Same network? Configuration required RADIUS Agent + eDirectory Agent Yes Yes Configure each agent to use a unique port to communicate with Filtering Service. By default, eDirectory Agent uses port 30700; RADIUS Agent uses port 30800. When adding agents to TRITON Web Security, use an IP address to identify one, and a machine name to identify the other. See the Transparent Identification of Users white paper for details. DC Agent + Logon Agent + RADIUS Agent Yes Yes This combination is rarely required. Configure each agent to use a unique port to communicate with Filtering Service. By default, DC Agent uses port 30600; Logon Agent uses port 30602; RADIUS Agent uses port 30800. Hardware recommendations for standalone Web Security deployments Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In standalone deployments, Network Agent (rather than Content Gateway or a thirdparty integration product) monitors network traffic and enables filtering of all protocols, including HTTP, HTTPS, and FTP. In a standalone deployment, one or more Network Agent instances: Detects all TCP/IP Internet requests (HTTP and non-HTTP) Communicates with Filtering Service to see if each request should be blocked Calculates the number of bytes transferred Sends a request to Filtering Service to log Internet activity The table below provides hardware recommendations for standalone deployments, based on network size. System needs vary depending on the volume of Internet traffic. The table does not include information for the TRITON management server (see System requirements for this version, page 2). The following baseline is used to create the recommendations: Deployment and Installation Center 51 Web Security Deployment Recommendations 1 - 500 users = 1 - 100 requests per second (rps) 500 - 2,500 users = 100 - 500 rps 2,500 - 10,000 users = 500 - 2,250 rps Important Do not install Websense components on a firewall machine. Firewall and Websense software function and performance may be affected. Each Network Agent machine must be positioned to see all Internet requests for the machines that it is assigned to monitor. eDirectory Agent or RADIUS Agent can be installed on the same machine as Filtering Service, or on a separate machine in the same network, but not on the same machine as Websense Log Server. If your network traffic exceeds these estimates, more powerful systems or greater distribution of components may be required.

High-speed disk access Microsoft SQL Server 2008 or 2005 required for Log Database To run both filtering and reporting on the same machine in the two smaller network sizes, increase the RAM to 6 GB (if supported by your operating system), and consider using a faster processor and hard drive to compensate for the increased load. For networks with 2,500-10,000 users, at least two Network Agent instances, running on separate machines, are required. The machines should have: Quad-Core Intel Xeon 5420 or better processor, 2.5 GHz or greater At least 1 GB of RAM Multiple Filtering Service machines may also be needed. Machine requirements depend on the number of users being monitored and filtered. Standalone deployment guidelines for Network Agent Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, and Web Security Gateway (Anywhere), v7.7.x In this topic Network Agent with multiple NICs, page 54 NAT and Network Agent, page 55 Network Agent manages Internet protocols (including HTTP, HTTPS, and FTP), by examining network packets and identifying the protocol. As with integrated proxies, firewalls, and network appliances, Network Agent can be configured to monitor HTTP requests, query Filtering Service to determine whether to permit or block each request, and then log the results of the query. Network Agent can Deployment and Installation Center 53 Web Security Deployment Recommendations also be configured to monitor, filter, and log non-HTTP requests (including requests that do not originate from an Internet browser). When Network Agent is used, it must be installed: Inside the corporate firewall Where it can see all Internet requests for the machines it is assigned to monitor Network Agent monitors and manages only the traffic that passes through the network device (typically a switch) to which it is attached. Multiple Network Agent instances may be needed, depending on: network size volume of Internet requests network configuration While a simple network may require only a single Network Agent, a segmented network may require (or benefit from) a separate Network Agent instance for each segment. Network Agent functions best when it is closest to the computers that it is assigned to monitor. For more information, see: Network Agent with multiple NICs, page 54 NAT and Network Agent, page 55 Positioning Network Agent in the network, page 55 Network Agent with multiple NICs Network Agent is capable of using more than one network interface card (NIC). Best practices suggest a maximum of 5 NICs. The NICs can be connected to ports on the same network device (switch or router), or to different network devices. If the machine running Network Agent has multiple NICs: Only one instance of Network Agent can be installed on the machine. The blocking or inject NIC (used to serve block pages) must have an IP address. Each NIC can be configured to monitor or block Internet requests, or both. Each NIC can be configured to monitor a different network segment. At least one NIC must be configured for blocking. When you configure separate network cards to monitor traffic and send block messages (shown in the illustration below): The monitoring and blocking NIC do not have to be assigned to the same network segment. 54 Websense Web Security Solutions Web Security Deployment Recommendations The monitoring NIC must be able to see all Internet traffic in the network segment that it is assigned to monitor. Multiple monitoring NICs can use the same blocking NIC. The blocking NIC must be able to send block messages to all machines assigned to the monitoring NICs, even if the machines are on another network segment. A monitoring NIC can be set for stealth mode. The blocking NIC must have an IP address (cannot be set to stealth mode). During installation, you specify which NIC is used by Websense software for communication and which NIC or NICs are used by Network Agent. For information on configuring multiple NICs, see the Network Agent Quick Start. NAT and Network Agent If you use Network Address Translation (NAT) on internal routers, Network Agent may be unable to identify the source IP address of client machines. When Network Agent detects traffic after it is passed through such a router, the agent sees the IP address of the router's external interface as the source of the request, rather than the IP address of the client machine. To address this issue, either disable NAT, or install Network Agent on a machine located between the NAT router and the monitored clients. Positioning Network Agent in the network Collection: Deployment and Installation Center | Product: Web Security | Version: 7.7.x Applies to: Web Filter, Web Security, and Web Security Gateway (Anywhere), v7.7.x In this topic Locating Network Agent in a single-segment network, page 56 Locating Network Agent in a multiple-segment network, page 57 Network Agent on a gateway, page 60 Network Agent must be able to see all outgoing and incoming Internet traffic on the network segment that it is assigned to monitor. If the Network Agent machine connects to a switch: Deployment and Installation Center 55 Web Security Deployment Recommendations Configure the switch to use a mirror or span port, and connect Network Agent to this port, to allow the agent to see Internet requests from all monitored machines. Note Not all switches support port spanning or mirroring. Contact the switch vendor to verify that spanning or mirroring is available, and for configuration instructions. Optionally, use a switch that supports bidirectional spanning. This allows Network Agent to use a single network interface card (NIC) to both monitor traffic and send block pages. If the switch does not support bidirectional spanning, the Network Agent machine must have at least 2 NICs: one for monitoring and one for blocking. Network Agent can also be installed on a dedicated machine, connected to an unmanaged, unswitched hub located between an external router and the network. To ensure that Network Agent is able to monitor the expected traffic, it must both be positioned properly and configured in TRITON - Web Security. See Network Agent configuration in the TRITON - Web Security Help for instructions. Locating Network Agent in a single-segment network A single segment network is a series of logically connected nodes (computers, printers, and so on) operating in the same portion of the network. In a single segment network, Filtering Service and Network Agent must be positioned to monitor Internet traffic across the entire network. 56 Websense Web Security Solutions Web Security Deployment Recommendations The following illustration shows the filtering components in a stand-alone Web Security deployment, installed in a central location to see both HTTP and non-HTTP traffic. Locating Network Agent in a multiple-segment network Depending on the device used to connect network segments, some traffic may not be sent to all segments. A router, bridge, or smart hub serves as traffic control, preventing unneeded traffic from being sent to a segment. In this environment: Filtering Service must be installed where it can receive and manage Internet requests from Network Agent and any integration product. Each Network Agent instance must be able to see all Internet requests on the segment or segments that it is configured to monitor. Deployment and Installation Center 57 Web Security Deployment Recommendations Multiple Network Agent instances may be needed to capture all Internet requests. A Network Agent can be installed on each segment to monitor the Internet requests from that segment. Note A limit of 4 Network Agents is suggested for each Filtering Service. It may be possible to use more agent instances, depending on system and network configuration and the volume of Internet requests. If multiple Network Agent instances are installed: Ensure that the instances are deployed so that, together, they monitor the entire network. Partial deployment results in incomplete filtering and loss of log data in network segments not visible to Network Agent. Each Network Agent instance must monitor a non-overlapping set of IP addresses. An overlap can result in inaccurate logging and network bandwidth measurements, and improper bandwidth-based filtering. The network segment or IP address range monitored by each Network Agent instance is determined by the NIC settings for the agent, configured in TRITON Web Security. See the TRITON - Web Security Help for instructions. Avoid deploying Network Agent across different LANs. If you install Network Agent on a machine in the 10.22.x.x network, and configure it to communicate with a Filtering Service machine in the 10.30.x.x network, communication may be slow enough to prevent Network Agent from blocking an Internet request before the site is returned to the user. Central Network Agent placement A network with multiple segments can be filtered from a single location. Install Filtering Service where it can receive Internet requests from each Network Agent and any integration product. If the network contains multiple switches, Network Agent instances are inserted into the network at the last switch in the series. This switch must be connected to the gateway that goes out to the Internet. In the following illustration: One Network Agent instance is installed with Filtering Service on Machine A. This machine is connected to the network via a switch that is configured to mirror or span the traffic of network Segment 1. A second Network Agent is installed on Machine B, which is connected to the same switch as Machine A. Machine B is connected to a different port that is configured to mirror the traffic of Segments 2 and 3. Each Network Agent is positioned to see all traffic for the network segment it monitors, and to communicate with other Websense components. 58 Websense Web Security Solutions Web Security Deployment Recommendations The switch is connected to the gateway, allowing the Network Agent instances to monitor network traffic for all network segments. Distributed Network Agent placement The network diagram below shows a single Filtering Service with 3 Network Agents, one for each network segment. A deployment like this might be useful in organizations with satellite offices, for example. Filtering Service (Machine C) must be installed where it is able to receive and manage Internet requests from each Network Agent instance and any integration product. Each Network Agent (machines A, B and C) is connected to the network segment it monitors via the switch’s span or mirror port. Deployment and Installation Center 59 Web Security Deployment Recommendations In the following illustration, the switches are not connected in a series. However, each switch is connected to the router, which is connected to the gateway. Network Agent on a gateway A gateway provides a connection between two networks. The networks do not need to use the same network communication protocol. The gateway can also connect a network to the Internet. Network Agent can be installed on the gateway machine, allowing Network Agent to manage and monitor all Internet traffic. The gateway can either be a third-party proxy server or a network appliance. Do not install Network Agent on a firewall. Also, if your network includes a software installation of Content Gateway, do not install Network Agent on the Content Gateway machine. (Content Gateway and Network Agent can reside on the same V-Series appliance.) 60 Websense Web Security Solutions Web Security Deployment Recommendations The following illustration shows Network Agent monitoring the Internet traffic at the proxy gateway or caching appliance directly attached to the firewall. Important The gateway configuration shown here is best used in small to medium networks. In larger networks, performance can suffer as a result of resource competition between the gateway software and Network Agent. Deployment and Installation Center 61 Web Security Deployment Recommendations Deploying Remote Filtering Server and Client Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x With all Web Security solutions, you have the option to use remote filtering software to manage Internet activity for machines that reside or travel outside your network. Remote Filtering Client is installed on each remote machine. The client software communicates with Remote Filtering Server, which acts as a proxy to Websense Filtering Service. Communication between the components is authenticated and encrypted. Note If you have Websense Web Security Gateway Anywhere, you can also use the hybrid service to monitor users outside your network. This does not require software installation on remote machines. When you install remote filtering components: Install Remote Filtering Server on a dedicated machine that can communicate with the Filtering Service machine. As a best practice, install Remote Filtering Server in the DMZ outside the firewall protecting the rest of the corporate network. This is strongly recommended. Do not install Remote Filtering Server on the same machine as Filtering Service or Network Agent. Each Filtering Service instance can have only one primary Remote Filtering Server.

Deployment and Installation Center 63 Web Security Deployment Recommendations Using the TRITON management server as policy source for filtering-only appliances Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x V10000, V10000 G2, and V5000 G2, v7.7.x It is possible to deploy Web Security components so that the central Policy Broker and Policy Server are installed on the TRITON management server, and Websense filtering only appliances use that machine as the full policy source. If you choose this deployment option, it is important to install your components in the following order. 1. Install Policy Broker, Policy Server, and (if you are installing Web Security Gateway Anywhere) Linking Service on the machine that will become the TRITON management server. See Installing Web Security components, page 392. 2. Set up the appliance to run in filtering only mode, specifying the Policy Broker machine (the future TRITON management server) as the policy source. 3. Create a TRITON management server with either the Web Security module only or the Web and Data Security modules of the TRITON Unified Security Center. See Creating a TRITON Management Server, page 180. 4. Install off-appliance components as necessary. See Installing Web Security components, page 392. 64 Websense Web Security Solutions 3 Deploying Web Security for a distributed enterprise Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Distributed enterprise networks may have many remote locations, ranging from dozens to thousands of small sites. Many of these sites have Internet access, but no dedicated IT staff. Some organizations use a decentralized network topology that provides each remote site with its own Internet connection. The challenge is to apply consistent, costeffective filtering of Internet requests across the entire organization. Remote sites must have Internet access. Internet access is provided by independent Internet service providers, often using low to medium-bandwidth connections. Web page requests are sent directly to the Internet and are not first routed through a central corporate network. Internet access must be filtered to permit only appropriate content. Cost considerations prohibit deploying a dedicated filtering server at each site. Given the relative low speed of each office’s Internet connection, a slightly slower response from the filtering product is acceptable. All remote sites can be filtered using the same policies. Websense Web Filter, Web Security, and Web Security Gateway are on-premises solutions in which Websense filtering components can be deployed regionally and communicate over the Internet to apply uniform filtering policies across all offices. Websense Web Security Gateway Anywhere is a hybrid solution, allowing a combination of on-premises and in-the-cloud filtering. For more information, see: Web Security basic distributed enterprise topology, page 66 Web Security filtering remote sites, page 70 Deployment and Installation Center 65 Deploying Web Security for a distributed enterprise Web Security distributed enterprise deployment models, page 74 Web Security distributed deployments and secure VPN connections, page 81 Web Security basic distributed enterprise topology Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Web Security and Web Security Gateway, page 66 Websense Web Security Gateway Anywhere, page 69 Web Security and Web Security Gateway To reduce network infrastructure costs, each remote-site firewall in a decentralized network is connected directly to the Internet, rather than to a corporate WAN. A small office/home office (SOHO) firewall is connected to an ISDN, DSL/cable, or T1 connection. Except for corporate application data that may use a virtual private network (VPN) connection, each outbound Internet request from a remote site is sent through a local Internet service provider (ISP) to the Internet. 66 Websense Web Security Solutions Deploying Web Security for a distributed enterprise The illustration below shows a sample network topology of this type of remote site for Websense Web Security. Deployment and Installation Center 67 Deploying Web Security for a distributed enterprise Websense Web Security Gateway adds Websense Content Gateway to the deployment, as shown below. Optionally, off-site users (remote users outside the corporate or remote-site network) can be filtered using Websense remote filtering software. This requires that Remote Filtering Server (not depicted) be deployed in the main site network and Remote Filtering Client be installed on each off-site machine. See Deploying Remote Filtering Server and Client, page 62. The above two illustrations show a high-level scheme only. Details about how Websense filtering components might be distributed across separate machines, 68 Websense Web Security Solutions Deploying Web Security for a distributed enterprise Content Gateway deployment, Network Agent placement, use of an integration product, and so forth are not included. Websense Web Security Gateway Anywhere With Web Security Gateway Anywhere, remote site and off-site users can be filtered through the hybrid service rather than by the filtering software installed at the main site. Deployment and Installation Center 69 Deploying Web Security for a distributed enterprise Web Security Gateway Anywhere software is installed at the main site. This may include: One or more Websense V-Series appliances running core filtering components, plus additional servers running reporting, management, and interoperability components. One or more Windows or Linux servers running core filtering and interoperability components, plus Windows servers running reporting and management components. Either Websense remote filtering software or the hybrid service can be used to manage Internet activity for remote sites or off-site machines. See the TRITON - Web Security Help for more information about configuring the hybrid service for off-site users. Web Security filtering remote sites Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Websense Web Security or Web Security Gateway, page 70 Websense Web Security Gateway Anywhere, page 72 Websense Web Security or Web Security Gateway In centralized organizations that route all outbound Internet requests through a single large Internet connection, the servers running Websense software are normally placed physically close to the firewall, proxy server, or network appliance. Remote sites in a distributed enterprise have a direct local connection to the Internet, and no centralized point of control. Rather than deploying Websense software at each remote-site firewall, you can deploy Websense components in a geographically central location. Since Websense software is accessible from the Internet, the Websense components should be protected by a firewall that allows URL lookup requests to pass through. Filtering is performed by the Websense components at the main site. Remote sites must be equipped with a firewall that can be integrated with Websense software (configured to check with Websense software to permit or block Web requests), or an instance of Websense Network Agent must be deployed at the remote site. Websense, Inc., has tested this configuration in cooperation with several of its integration partners. A full list of supported integration products can be found at: 70 Websense Web Security Solutions Deploying Web Security for a distributed enterprise www.websense.com/global/en/Partners/TAPartners/SecurityEcosystem/ Centralized filtering Provides distributed enterprises with Websense filtering for each remote site. It also: Eliminates the need for a separate Websense software installation at each location. Provides uniform filtering policies at each remote site. Eliminates the cost of additional hardware to provide filtering servers at each remote site. Allows the enterprise to centrally configure, administer, and maintain a limited number of Websense filtering machines. The following illustration shows the basic sequence of events involved in filtering a client machine at a remote site. 1. A user requests a Web page. Deployment and Installation Center 71 Deploying Web Security for a distributed enterprise 2. The request is directed through the local firewall to Web Security software at the main site via the Internet. 3. Web Security software responds via the Internet, either permitting or blocking the request. 4. The user is given access to the site or sees a block page. In the case of multiple remote sites, each remote site communicates with Websense components at the main site in the same manner shown above. Off-site user machines (like laptops used by travelers) may be filtered using Websense remote filtering software. See Deploying Remote Filtering Server and Client, page 62. Websense Web Security Gateway Anywhere In a Web Security Gateway Anywhere deployment, remote sites can be filtered either by the hybrid service or by Websense security solutions installed at the main site. Using the hybrid service may address network latency issues, because remote sites and off-site users are filtered by the nearest Websense hybrid service cluster. 72 Websense Web Security Solutions Deploying Web Security for a distributed enterprise The following illustration shows how remote-site filtering works via the hybrid service. A user’s request for a Web page is directed to the hybrid service, which permits or blocks the request based on the applicable policy. Policy settings are defined at the main site and uploaded automatically to the hybrid service at preset intervals. User information, for user- or group-based filtering, is also uploaded. Deployment and Installation Center 73 Deploying Web Security for a distributed enterprise Log data for reporting is downloaded from the hybrid service to the main site automatically and is incorporated into the Websense Log Database (at the main site). Thus, reports can cover users at all offices. Off-site users may be filtered by the hybrid service, or using Websense remove filtering software. See Deploying Remote Filtering Server and Client, page 62. Web Security distributed enterprise deployment models Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Sites in a region, page 74 Expanding sites in a region, page 76 National or worldwide offices, page 78 Deployment scenarios vary with different enterprise configurations. For example, an organization with 50 remote sites, all located in the same general region, deploys Websense software differently than a company with remote sites spread throughout the world. This section discusses 3 basic example models for distributed enterprises: Sites in a region, page 74: Remote sites located within one region Expanding sites in a region, page 76: Remote sites located within one region, with a growing number of employees or sites (or both) National or worldwide offices, page 78: Remote sites located nationally or globally Sites in a region The simplest Websense deployment for a distributed enterprise is a network with remote sites in a single region, such as San Diego County, California, U.S.A. Most organizations with sites like this can use a single Websense Web Security or Web 74 Websense Web Security Solutions Deploying Web Security for a distributed enterprise Security Gateway deployment, centrally located within that region, to provide filtering for all clients. See the following illustration. Each remote site would be filtered as shown in the illustration under Websense Web Security or Web Security Gateway, page 70. The site in which Websense software is deployed is represented as the “main site”, but need not be truly a main site in your organization. It is whichever one houses Websense software. Off-site users, not shown in the above illustration, can be filtered using Websense remote filtering software. See Deploying Remote Filtering Server and Client, page 62. Deployment and Installation Center 75 Deploying Web Security for a distributed enterprise Expanding sites in a region Some organizations deploy Web Security or Web Security Gateway within a given region and later decide to increase the number of remote sites in that area. To compensate for the additional sites and employees, the organization can: Improve the performance of the machines running Websense components. Increasing the RAM and CPU, and installing faster hard drives on the Websense machines allows Websense software to respond to an increased number of requests without additional latency. This type of upgrade can help with a moderate increase in head count, or the addition of a few more offices. Deploy additional machines to run Websense components. If a significant number of new users or sites is added, the deployment of additional instances of 76 Websense Web Security Solutions Deploying Web Security for a distributed enterprise certain Websense components, such as Filtering Service and Network Agent, distributes the load and provides optimum performance for each remote site. Additional instances of Websense components can be deployed within the region as the number of offices continues to grow. Off-site users, not shown in the preceding illustration, can be filtered by Websense remote filtering software. See Deploying Remote Filtering Server and Client, page 62. Deployment and Installation Center 77 Deploying Web Security for a distributed enterprise National or worldwide offices Websense Web Security or Web Security Gateway Some organizations have hundreds of remote sites spread through a country or around the world. In such cases, one or two Web Security or Web Security Gateway installations are not enough because: Each remote site would be geographically distant from the Websense components. Request lookups would have to travel farther over the Internet to reach Websense software. This distance increases the total latency of the response and may lead to slower Internet access for end users. Large numbers of employees generate more Internet requests than recommended for one or two Websense machines, leading to delays in returning Web pages to requesting clients. These organizations should divide their sites into logical regions and deploy Websense software in each region. For example, a distributed enterprise might group their United States sites into a western region, a central region, and an eastern region. Websense software is deployed at a central site in each region. The logical division of sites into regions depends on the location and grouping of remote sites and the total number of employees at each site. For example, a company with a large number of remote sites in a concentrated area, such as New York City, may need to deploy multiple machines running Websense software within that area. Or an enterprise may only have three sites in California with 100 to 250 employees each. In this case, a single Websense software installation might be deployed for all three sites. This enterprise also can deploy Websense software locally at each site (rather than using a distributed approach), particularly if IT staff is present at each location.You may consider installing instances of Filtering Service, Network Agent, and possibly Policy Server and Content Gateway to improve response time for filtering. Given the significant number of variables, large organizations should contact a Websense partner or Websense Sales Engineering to plan a rollout strategy before deployment. Websense Web Security Gateway Anywhere Websense Web Security Gateway Anywhere is particularly well-suited for organizations with sites distributed nationally or worldwide. Single main site An organization with one main site (such as headquarters office or main campus) and multiple, geographically dispersed remote or branch sites can deploy Websense software at the main site (with main-site users filtered by the on-premises 78 Websense Web Security Solutions Deploying Web Security for a distributed enterprise components) and have all remote sites filtered through the hybrid service. See the following illustration. Off-site users, not shown in the above illustration, may either be managed by the hybrid service, or with Websense remote filtering software. See Deploying Remote Filtering Server and Client, page 62. Multiple large sites Organizations with multiple large sites (such as main headquarters and regional headquarters) can deploy on-premises filtering at the larger sites while filtering small, remote sites through the hybrid service. Though the illustration shows a V-Series Deployment and Installation Center 79 Deploying Web Security for a distributed enterprise appliance deployment, this can also be accomplished with software-only deployments. When there are multiple on-premises deployments of Web Security Gateway Anywhere components: There must be only one Policy Broker and one Sync Service in the entire deployment (at the main site).

Content Gateway deployment issues Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Security Gateway and Gateway Anywhere, v7.7.x In this topic Proxy deployment options, page 84 User authentication, page 85 HTTPS content inspection, page 87 Handling special cases, page 87 Planning to deploy Websense Content Gateway as a proxy in your network should include physical requirements, such as: data center location and space power and cooling requirements for hardware required rack space connectivity to existing or extended network topology Also consider: Content Gateway system requirements (hardware and operating system) Advantages and disadvantages of proxy network configuration options User authentication and identification options How to configure and use HTTPS content inspection A plan for handling special proxy/client issues Proxy deployment options Websense Content Gateway is used in either an explicit or transparent proxy deployment. With an explicit proxy deployment, client software, typically a Web browser, is configured to send a request for Internet content directly to Content Gateway. In a transparent proxy deployment, a client request for Web content is intercepted (usually by a router) and sent to the proxy. The client is unaware that it is communicating with a proxy. 84 Web Security Gateway and Gateway Anywhere Content Gateway Deployment Both options have advantages and disadvantages. See Content Gateway explicit and transparent proxy deployments, page 88 for more information. Management clustering A Websense Content Gateway deployment can scale from a single node to multiple nodes to form a management cluster. With management clustering, all the nodes in the cluster share configuration information. A configuration change on one node is automatically propagated all other nodes. When SSL Manager is enabled to perform HTTPS content inspection, SSL configuration information can also be propagated around the cluster, however it uses a different mechanism that requires separate configuration. See Clusters in Content Gateway Manager Help for information about configuring Content Gateway clusters. IP spoofing The IP spoofing feature directs the proxy to use the client IP address when establishing a connection to an origin server, rather than the proxy’s IP address. With this option, a request appears to be from the client, not the proxy. IP spoofing is supported in transparent proxy deployments only. If IP spoofing is implemented, the client IP address is used for all HTTP and HTTPS requests in transparent proxy deployments. Warning Deploying IP spoofing requires precise control of the routing paths on your network, overriding the normal routing process for traffic running on TCP ports 80 and 443. With IP spoofing enabled, traditional debugging tools such as traceroute and ping have limited utility. You might want to implement this feature, for example, if an upstream network device is used to log HTTP/S traffic, perform authentication, or access controls based on the client IP address. For information about how to enable IP spoofing, see Transparent Proxy Caching and ARM in the Content Gateway Manager Help. User authentication User authentication is the process of verifying a user via a username and password. Several types of user authentication are supported by Content Gateway. User identification is the process of identifying a user based on the client IP address. TRITON - Web Security offers a robust set of user identification agents. Deployment and Installation Center 85 Content Gateway Deployment Content Gateway user authentication Content Gateway can be configured for transparent user authentication -- with Integrated Windows® Authentication (IWA) or Legacy NTLM -- in which users are not prompted for credentials. Alternatively, Content Gateway can be configured for prompted (or manual) authentication, in which users are required to enter a username and password to obtain network access. Note Not all Web browsers support both transparent and prompted authentication modes. See the v7.7 Websense Content Gateway Release Notes for specific browser limitations. In the manual authentication process, Content Gateway prompts a user for proxy login credentials when that user requests Internet content. After the user enters those credentials, the proxy sends them to a directory server that validates the data. If the directory server accepts the user’s credentials, the proxy delivers the requested content. Otherwise, the user’s request is denied. The issue of proxy user authentication is important in a deployment in which multiple proxies are chained. Authentication by the proxy closest to the client is preferred, but may not be possible given a particular network’s configuration. Other issues include whether Content Gateway is chained with a third-party proxy and which proxy is designated to perform authentication. See In a proxy chain, page 96 for more information. Websense Content Gateway supports the following user authentication methods: Integrated Windows Authentication (with Kerberos) Legacy NTLM (Windows NT® LAN Manager, NTLMSSP) LDAP (Lightweight Directory Access Protocol) RADIUS (Remote Authentication Dial-In User Service) Content Gateway supports both transparent and prompted authentication for Integrated Windows Authentication and Legacy NTLM. LDAP and RADIUS support prompted authentication. Content Gateway also supports multiple realm authentication. Multiple realm authentication is for environments that have multiple domains that are essentially isolated for the purposes of user authentication by a lack of mutual inbound and outbound trust relationships. Therefore, users in these domains must be authenticated by a domain controller within their domain. Multiple realm authentication allows distinct authentication rules to be written for each domain, thereby supporting the ability to use multiple authentication methods (IWA, Legacy NTLM, LDAP) at the same time. See Security in the Content Gateway Manager Help for detailed information about configuring these proxy user authentication options. 86 Web Security Gateway and Gateway Anywhere Content Gateway Deployment TRITON - Web Security user identification You can configure user identification in TRITON - Web Security rather than user authentication on the proxy. Methods of user identification include the use of Websense transparent identification agents like Logon Agent or DC Agent, which identify users transparently. Prompted authentication, which requires users to enter login credentials, can also be configured in TRITON - Web Security. See User Identification in the TRITON - Web Security Help for more information. HTTPS content inspection When you use Content Gateway with HTTPS (SSL Manager) enabled, HTTPS data can be decrypted, inspected, and then re-encrypted as it travels from the client to the origin server and back. Enabling this feature also means that traffic from the server to the client can be inspected for Web 2.0 and uncategorized sites. The SSL feature includes a complete set of certificate-handling capabilities. See the Content Gateway Manager online Help for information on managing certificates. Deploying Content Gateway with SSL Manager enabled may require the following modifications to your system: Creation of trusted Certificate Authority (CA) certificates for each proxy to use for SSL traffic interception, and the installation of those certificates in each trusted root certificate store used by proxied applications and browsers on each client In explicit proxy deployments, additional client configuration in the form of Proxy Auto-Configuration (PAC) files or Web Proxy Auto-Discovery (WPAD) In transparent proxy deployments, integration with WCCP v2-enabled network devices Note HTTPS content inspection can also affect system hardware resources like processing capacity and memory requirements. When Content Gateway is configured to handle HTTPS traffic, you can specify categories of Web sites, individual Web sites, and clients for which decryption and inspection are always bypassed. See SSL Decryption Bypass in TRITON - Web Security Help for more information. Handling special cases Any Content Gateway deployment must be able to handle Web site requests and applications that are not compatible with the proxy or that should bypass the proxy. For example, requests for data from some internal, trusted sites could be configured to bypass the proxy, for system performance reasons. In explicit proxy deployments, a PAC file can be used to list the traffic that is allowed to bypass proxy inspection. In transparent proxy deployments, the proxy must be installed in a way that allows static Deployment and Installation Center 87 Content Gateway Deployment bypass. See the “Static bypass rules” section of Transparent Proxy Caching and ARM in Content Gateway Manager Help. See, also: Web sites that have difficulty transiting Content Gateway. Content Gateway explicit and transparent proxy deployments Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Security Gateway and Gateway Anywhere, v7.7.x In this topic Explicit proxy deployment, page 88 Transparent proxy deployment, page 89 Websense Content Gateway provides the following proxy deployment options: Explicit proxy deployment, where the user’s client software is configured to send requests directly to Content Gateway Transparent proxy deployment, where user requests are automatically redirected to a Content Gateway proxy, typically by a switch or router, on the way to their eventual destination For more information about configuring explicit and transparent proxy options in Content Gateway, see Explicit Proxy, Transparent Proxy, and ARM in the Content Gateway Manager Help. Explicit proxy deployment Use of Content Gateway in an explicit proxy deployment is an easy way to handle Web requests from users. This type of deployment is recommended for simple networks with a small number of users. Explicit proxy is also used effectively when proxy settings can be applied by group policy. It requires minimal network configuration, which can be an advantage for troubleshooting efforts. For explicit proxy deployment, individual client browsers may be manually configured to send requests directly to the proxy. They may also be configured to download proxy configuration instructions from a Proxy Auto-Configuration (PAC) file. A group policy that points to a PAC file for configuration changes is a best practice for explicit proxy deployments. Another option is the use of Web Proxy AutoDiscovery (WPAD) to download configuration instructions from a WPAD server. See Explicit Proxy in Content Gateway Manager Help for a sample PAC file and more information about how to implement these options. See also: PAC file best practices. 88 Web Security Gateway and Gateway Anywhere Content Gateway Deployment Exception handling instructions can also be included in the PAC file or WPAD instructions. For example, requests for trusted sites can be allowed to bypass the proxy. Disadvantages of explicit proxy deployment include a user’s ability to alter an individual client configuration and bypass the proxy. To counter this, you can configure the firewall to allow client traffic to proceed only through the proxy. Note that this type of firewall blocking may result in some applications not working properly. You can also use a Group Policy Option (GPO) setting to prevent users from changing proxy settings. If you cannot enforce group policy settings on client machines, this type of configuration can be difficult to maintain for a large user base because of the lack of centralized management. Note Non-browser client applications that cannot specify a proxy server may not work with explicit proxy deployment. Transparent proxy deployment In a transparent proxy deployment, the user’s client software (typically a browser) is unaware that it is communicating with a proxy. Users request Internet content as usual, without any special client configuration, and the proxy serves their requests. The Adaptive Redirection Module (ARM) component of Websense Content Gateway processes requests from a switch or router and redirects user requests to the proxy engine. The proxy establishes a connection with the origin server and returns requested content to the client. ARM readdresses returned content as if it came directly from the origin server. For more information, see Transparent Proxy and ARM in Content Gateway Manager Help. Note that in a transparent proxy deployment, all Internet traffic from a client goes through the proxy (not just traffic from Web browsers), including: traffic tunneled over HTTP and HTTPS by remote desktop applications instant messaging clients software updaters for Windows and anti-virus applications custom internal applications Many of these programs are not developed with proxy compatibility in mind. For a successful transparent proxy deployment, the network must be configured to allow the proxy’s static bypass feature to work. See the “Static bypass rules” section of Transparent Proxy and ARM in Content Gateway Manager Help. Because traffic management is centralized, users cannot easily bypass the proxy. This type of deployment requires the implementation of at least one other network device that is not required in the explicit proxy deployment. Added equipment presents compatibility issues, as all network devices must work together smoothly and Deployment and Installation Center 89 Content Gateway Deployment efficiently. The overall system is often more complex and usually requires more network expertise to construct and maintain. The use of a Layer 4 switch or WCCPv2-enabled router to redirect traffic in a transparent proxy deployment can provide redundancy and load distribution features for the network. These devices not only route traffic intelligently among all available servers, but can also detect whether a proxy is nonfunctional. In that case, the traffic is re-routed to other, available proxies. Exception handling can be included in switch or router configuration. For example, requests for data from some internal, trusted sites can be allowed to bypass the proxy. Layer 4 switch You can implement policy-based routing (PBR) for a transparent proxy deployment with the use of a Layer 4 switch, which can be configured to redirect a request to the proxy, as follows: 1. Create an access control list (ACL) that identifies the Web traffic that should be intercepted. 2. Develop a route map to define how the intercepted Web traffic should be modified for redirection. 3. Apply a “redirect to proxy” policy to the switch interface. See Transparent Proxy and ARM in Content Gateway Manager Help for more information about the use of a Layer 4 switch. WCCP-enabled router Note Websense Content Gateway supports WCCP v2 only. WCCP is a protocol used to route client request traffic to a specific proxy. A WCCP-enabled router can distribute client requests based on the proxy server’s IP address, routing traffic to the proxy most likely to contain the requested information. The router may use Generic Routing Encapsulation (GRE) to forward IP packets to the proxy. GRE is a tunneling protocol that allows point-to-point links between multiple traffic routing hops. A router may also use Layer 2 (L2), which does not use GRE. Websense recommends the use of L2 if the router supports it. With L2 redirection, Content Gateway must be on the same subnet as the WCCP device (that is, Layer 2 adjacent). Important If using L2 the router or switch must be Layer 2-adjacent (in the same subnet) as Content Gateway. 90 Web Security Gateway and Gateway Anywhere Content Gateway Deployment A proxy and a router communicate via a set of WCCP “Here I am” and “I see you” messages. A proxy that does not send a “Here I am” message for 30 seconds is removed from service by the router, and client requests that would have been directed to that proxy are sent to another proxy. The following illustration shows an example transparent proxy deployment. Deployment and Installation Center 91 Content Gateway Deployment A comparison of how some activities are handled in explicit and transparent proxy deployments appears in the following table: Activity Explicit Proxy Deployment Transparent Proxy Deployment Proxy Chain Client HTTP request Direct connection to proxy by browser to port 8080 (default) Redirected to proxy by network device using GRE encapsulation or by rewriting the L2 destination MAC address to the proxy’s address Direct connection to parent proxy from child proxy Exception management Exclude site, CIDR, etc., using browser configuration settings and PAC file settings. Static or dynamic bypass rules Child/parent proxy configuration rules Proxy user authentication Proxy challenge using 407 Proxy Authentication Required code Challenge using server-based authentication scheme (client is not aware of proxy) Proxies in a chain may share credential information, or a single proxy in the chain can perform authentication.

The proxy can also be deployed in a chain, either with other Content Gateway proxies or third-party proxies. This section describes some examples of these deployment scenarios. Highly available Web proxy A highly available Web proxy provides continuous, reliable system operation. Minimizing system downtime increases user access and productivity. Proxy high availability may be accomplished via a proxy cluster that uses various failover contingencies. Such deployments may involve either an explicit or transparent proxy configuration, load balancing, virtual IP addresses, and a variety of switching options. This section summarizes some possibilities for highly available Web proxy deployments. Using explicit proxy As previously mentioned for the explicit proxy deployment, clients are specifically configured to send requests directly to a proxy. The configuration can be accomplished manually, or via a PAC file or a WPAD server. An explicit proxy deployment for high availability can benefit from the use of virtual IP failover. IP addresses may be assigned dynamically in a proxy cluster, so that one proxy can assume traffic-handling capabilities when another proxy fails. Websense Content Gateway maintains a pool of virtual IP addresses that it distributes across the nodes of a cluster. If Content Gateway detects a hard node failure (such as a power supply or CPU failure), it reassigns IP addresses of the failed node to the operational nodes. Deployment and Installation Center 93 Content Gateway Deployment Active/Standby In the simple case of an active/standby configuration with 2 proxies, a single virtual IP address is assigned to the virtual IP address “pool.” The virtual IP address is assigned to one proxy, which handles the network traffic that is explicitly routed to it. A second proxy, the standby, assumes the virtual IP address and handles network traffic only if the first proxy fails. This deployment assumes the proxy machines are clustered in the same subnet, and management clustering is configured (that is, both proxies have the same configuration). Below is an example. Active/Active In an active/active configuration with 2 proxies, more than one virtual IP address is assigned to the virtual IP address pool. At any point in time, one proxy handles the network traffic that is explicitly directed to it. This deployment is scalable for larger numbers of proxies. Clients requesting the IP address of a proxy can be crudely distributed using round robin DNS. Round robin DNS is not a true load balancing solution, because there is no way to detect load and redistribute it to a less utilized proxy. Management clustering should be configured. An increase in the number of proxy machines makes the use of a PAC file or WPAD for specifying client configuration instructions convenient. A PAC file may be modified to adjust for proxy overloads, in a form of load balancing, and to specify Web site requests that can bypass the proxy. 94 Web Security Gateway and Gateway Anywhere Content Gateway Deployment As with the active/standby configuration, an available proxy can assume a failed proxy’s load. Below is an example. With load balancing A load balancer is a network device that not only distributes specific client traffic to specific servers, but also periodically checks the status of a proxy to ensure it is operating properly and not overloaded. This monitoring activity is different from simple load distribution, which routes traffic but does not account for the actual traffic load on the proxy. A load balancer can detect a proxy failure and automatically re-route that proxy’s traffic to another, available proxy. The load balancer also handles virtual IP address assignments. Below is an example. Using transparent proxy In a transparent proxy deployment for high availability, traffic forwarding may be accomplished using a Layer 4 switch or a WCCP v2-enabled router. Routers or Deployment and Installation Center 95 Content Gateway Deployment switches can redirect traffic to the proxy, detect a failed proxy machine and redirect its traffic to other proxies, and perform load balancing. Using a Layer 4 switch In one simple form of transparent proxy, a hard-coded rule is used to write a proxy’s Media Access Control (MAC) address as the destination address in IP packets in order to forward traffic to that proxy. Traffic that does not include the specified proxy address for forwarding is passed directly to its destination. See below for an example. As described for the explicit proxy, virtual IP addresses can be used in this scenario to enhance availability in case a proxy machine fails. Using a WCCPv2-enabled router WCCP is a service that is advertised to a properly configured router, allowing that router to automatically direct network traffic to a specific proxy. In this scenario, WCCP distributes client requests based on the proxy server’s IP address, routing traffic to the proxy most likely to contain the requested information. In a proxy chain Websense Content Gateway can be deployed in a network that contains multiple proxy machines, including one or more third-party proxies. A proxy chain deployment can involve different scenarios, depending on where Content Gateway is located in relation to the client. The proxy that is closest to the client is called the downstream proxy. Other proxies are upstream. 96 Web Security Gateway and Gateway Anywhere Content Gateway Deployment Below is a simple example of proxy chaining. On the left, Websense Content Gateway is the downstream proxy. On the right, Websense Content Gateway is upstream. See Chaining Content Gateway with other proxies, page 99, for specific instructions on using Blue Coat® ProxySG® or Microsoft ISA/TMG server as the downstream proxy. Websense Content Gateway is downstream A simple deployment has Websense Content Gateway as the downstream proxy, closest to the client. In this scenario, Websense Content Gateway security features are well positioned for maximum protection and network performance. In this scenario, use of Websense Content Gateway authentication to validate client credentials is preferred. You must disable authentication on the third-party proxy. However, if the upstream third-party proxy requires authentication, you must disable authentication on Content Gateway and enable the pass-through authentication feature via an entry in the records.config file (in the /WCG/config/ directory by default). An example records.config entry is as follows: CONFIG proxy.config.http.forward.proxy_auth_to_parent INT 1 You can then use a transparent identification agent (for example, Logon Agent) to facilitate client identification. Content Gateway can additionally send the client IP address to the upstream third-party proxy using the X-Forwarded-For HTTP header via an entry in records.config. To enable this function, the following entry would be made: CONFIG proxy.config.http.insert_squid_x_forwarded_for INT 1 Deployment and Installation Center 97 Content Gateway Deployment The X-Forwarded-For HTTP header is the de facto standard for identifying the originating IP address of a client connecting through an HTTP proxy. Some proxies do not utilize the X-Forwarded-For header. For information about installing and deploying transparent identification agents, see Deploying transparent identification agents, page 48, and Installing Web Security components, page 392. Websense Content Gateway is upstream When Content Gateway is the upstream proxy, the downstream third-party proxy can perform authentication and send client IP and username information in the HTTP request headers. Content Gateway authentication must be disabled. In this scenario, caching must be disabled on the third-party proxy. Allowing the thirdparty proxy to cache Web content effectively bypasses Content Gateway’s inspection capabilities for any Web site that was successfully accessed previously from the thirdparty proxy. For an upstream Websense Content Gateway to identify users: Enable authentication on the third-party proxy. Designate Content Gateway as the parent proxy in the third-party proxy’s configuration. Set the Read authentication from child proxy option in the Websense Content Gateway Configure pane (Configure > My Proxy > Basic > Authentication). This option allows Content Gateway to read the X-Forwarded-For and X-Authenticated-User HTTP headers. The downstream third-party proxy passes the client IP address via the X-Forwarded-For header and the user domain and username in the X-Authenticated-User header. If the third-party proxy can send the X-Forwarded-For header but not the X-Authenticated-User header, the following step is also required: Deploy a transparent identification agent to facilitate client identification by Content Gateway. See Deploying transparent identification agents, page 48, and Installing Web Security components, page 392. Websense Content Gateway can be configured to read authentication from the following proxies in the downstream position: Blue Coat ProxySG 210 and later Microsoft Internet Security and Acceleration (ISA) Server 2004 and later For detailed configuration instructions for Blue Coat ProxySG and Microsoft ISA/ TMG server, see Chaining Content Gateway with other proxies, page 99. 98 Web Security Gateway and Gateway Anywhere Content Gateway Deployment Proxy cache hierarchy Another form of proxy chain is a flexible proxy cache hierarchy, in which Internet requests not fulfilled in one proxy can be routed to other regional proxies, taking advantage of their contents and proximity. For example, a cache hierarchy can be created as a small set of caches for a company department or a group of company workers in a specific geographic area. In a hierarchy of proxy servers, Content Gateway can act either as a parent or child cache, either to other Content Gateway systems or to other caching products. Having multiple parent caches in a cache hierarchy is an example of parent failover, in which a parent cache can take over if another parent has stopped communicating. As mentioned earlier, the increasing prevalence of dynamic, user-generated Web content reduces the need for Content Gateway caching capabilities. See Content Gateway Manager Help (Hierarchical Caching) for more information on this topic. SSL chaining Routing SSL traffic in a proxy chain involves the same parent proxy configuration settings used with other proxy-chained traffic. You identify the ports on which HTTPS requests should be decrypted and policy applied when SSL is enabled in the Protocols > HTTP > HTTPS Ports option in the Configure tab. Parent proxy rules established in parent.config for HTTPS traffic (destination port 443) determine the next proxy in the chain for that traffic. Enable the Configure tab Content Routing > Hierarchies > HTTPS Requests Bypass Parent option to disable SSL traffic chaining when all other traffic is chained. If you want to exclude SSL traffic from the parent proxy and tunnel the traffic directly to the origin server, enable the Tunnel Requests Bypass Parent option in the Configure tab Content Routing > Hierarchies. This option can be used for any tunneled traffic.

Sector Government agencies and organizations that are affiliated with the government are subjected to special requirements and regulations imposed by the government office, such as DIACAP for units and contractors related to the US Department of Defense and FISMA for US federal agencies and their contractors. For public companies, additional regulations may apply (such as the SarbanesOxley Act in the U.S., or regulations that are published by the regulatory body of the relevant stock markets). General Most organizations want to keep their marketing information away from competitors: Upcoming press releases Marketing campaigns Leads Existing customer data Many organizations have individualized needs for data protection that might not fall into typical categories, but Data Security can accommodate them. The TRITON - Data Security first-time policy wizard assists you in defining your region and industry and it displays the relevant policies, making it easier to select them. Besides predefined policies, you may want to protect specific information, such as: 104 Define Product Name Variable Planning Data Security Deployment Designs Drawings Marketing materials Legal documents Strategic planning documents, such as business plans Financial and pricing information All documents marked “Confidential” Determining where your confidential data resides Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.7.x In this topic: Corporate file servers and shared drives, page 105 In-house databases, page 106 Based on experience from numerous data-loss protection deployments, it’s evident that most sensitive company information resides within: Corporate file servers or shared drives In-house databases Personal laptops, workstations and removable media Corporate file servers and shared drives There are a few ways to determine where your confidential information is stored: Ask Talk to appropriate data owners in your organization and they may point you to relevant locations. This may cover a big part of the information that needs to be protected and is a good start. Your review of locations based on their revelations will undoubtedly reveal other critical data branchings and parallel storage places. Discover Use Websense Data Security to classify file servers, shared drives, and endpoints by running it with the relevant predefined policies enabled. This should give you bulk estimations of where data is located in your enterprise. Combining the results gives you a good idea of the location of your confidential information. Define Book Name Variable 105 Planning Data Security Deployment In-house databases As in case of file servers and shared drives, the best ways to understand which databases are critical is to ask: Talk to people that manage in-house applications relying on internal databases (such as customer relations, orders processing, and accounting). Talk to database administrators (DBAs) and find out what are the most accessed databases. The more a database is accessed, the more chances there are for data loss. Your IT department may also be able to elaborate on discoveries from both instances described above. Discover: Use Websense Data Security to classify databases by running it with the relevant predefined policies enabled. This should let you know primarily where your vital records are located. Based on the above information, you can narrow down the most critical database servers, databases and tables to protect. Determining your information flow Deployment and Installation Center | Data Security Solutions | Version 7.7.x Analyze the flow of information through your enterprise today. Where is information typically coming from? Internal users? Partners? Vendors? Where does it need to be sent? What are all the potential pathways for information? What processes are in place, if any, to govern data flow? How many HTTP, SMTP and FTP exits or egress points are there in the organization? These questions are vital to ensuring that protector(s) are placed appropriately so that nothing escapes analysis. Defining the business owners for the data Deployment and Installation Center | Data Security Solutions | Version 7.7.x The business owners of information normally come from the departments where the information was created. For example, if you wish to protect marketing materials, the head of marketing is normally the business owner, and should be consulted about deployments. (He/she may delegate the responsibility to other people in his/her department.) Normally, marketing principals—and principals from other departments—would want to get notifications about data losses containing 106 Define Product Name Variable Planning Data Security Deployment information originating from their department (even and especially if the sender is from a different department). Deciding who will manage incidents Deployment and Installation Center | Data Security Solutions | Version 7.7.x How should you delegate incident management across your organization? As in the case of business owners, you should identify who is responsible for data management in various departments. If you are unsure who that person is, you may either consult with the department manager or train one of the employees that you trust from that department. Once incident managers are identified, you can assign the proper roles and policy category groups to the relevant users through the TRITON - Data Security Web user interface. Planning access control Deployment and Installation Center | Data Security Solutions | Version 7.7.x Standard network installations provide access control (preventing personnel from viewing unauthorized files) by giving each user a login and password, and authorizing each user to view only the network directories required for the user's job function. However, authorized users can still send content they are authorized to use to unauthorized recipients. Define Product Name Variable augments access control by providing Information Distribution Management (IDM) capabilities, thereby greatly enhancing the level of information security. Websense Data Security protects digital content from being sent from your company’s network to people outside of the company, as well as protecting classified information from being sent to unauthorized users within the local network. Typically, these user privileges were defined individually, without considering grouping or security clearances for groups of people. Utilizing data security capabilities involves delineating users as belonging to groups or security levels, enabling a more sophisticated, higher level of control over classified data. Naturally, when considering the policies discussed in this chapter, it is important to consider how these policies are impacted by or impact other content policies in your company. The TRITON - Data Security software has the flexibility to accommodate the full range of enterprise security needs. Define Book Name Variable 107 Planning Data Security Deployment Analyzing network structure Deployment and Installation Center | Data Security Solutions | Version 7.7.x To best employ data security, you need to analyze your network structure, determine the location of confidential information, note which documents need to be protected and where they are located, and whether you need to make changes to the network directory structure in order to group documents differently for security purposes. In most organizations, user rights have been determined and built into the network directory structure, according to your organization's logic. You may conclude that the network configuration is fine as it is, or that the internal network definitions change to some degree due to today's higher security needs. Any changes you need to implement internally in the directory structure should be implemented with these increased security measures in mind. Structural guidelines It is possible to configure the system so that a particular user cannot access a certain document through the network, but can receive the document by email. For example, a manager would not want employees to access documents in his or her personal folder, but would want to be able to send the documents to them by email. It is therefore important that you perform this analysis together with the network administrator, so that your desired changes will be implemented internally in a smooth, logical fashion, as well as within the Websense structure. Typically, your network directories are organized functionally, according to the different business units in the company. Within this structure, functional groups are usually entitled to look at documents within their business unit. We recommended that you use this as your process map: Take a network map of all the directories, and look at how the network access is organized Determine what types of classified documents you have, and where they are located Determine whether documents of similar confidentiality are together in similar directories Organize/group information that is critical to your organization and information whose security is legally mandated. For example, financial institutions may start by considering customer data (such as Social Security numbers or account numbers) and highly confidential business information Organize/group important proprietary and confidential information with medium or low change-frequency Arrange all major information assets within your organization so that you understand data locations, relationships and security-value hierarchies 108 Define Product Name Variable Planning Data Security Deployment The result of this analysis should be a table corresponding to the directories in the network that need to be protected, indicating what types of users should be able to receive those files and to provide a look at access issues. You may want to rearrange some areas of your network access, and set the data security accordingly. See below for recommended procedures. Planning network resources Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.7.x In this topic: Allocating disk space, page 109 Modifying the disk space setting, page 110 Distributing resources, page 111 To decide on things like disk space allocation, number of servers, and network distribution, start by answering these questions: What volume of daily data do you expect in the number of transactions? What is your user count? Are you covering geographically distributed offices? What is your user directory structure (Active Directory, ADAM, Domino) and the IP addresses of the LDAP servers? Which ports are used and what are the port numbers? Allocating disk space Disk space for archiving fingerprint and forensic repositories is allocated by the Websense Data Security by default. The default settings are the nominal values defined by Websense; however, you can modify these values. The tables below indicates the default and maximum disk space for archives, forensics repository and endpoint client incident storage, log file and fingerprint storage. Define Book Name Variable 109 Planning Data Security Deployment On TRITON management server Type Description Default Setting Max Disk Space Archive The disk space of the incident archive folder on a local or external partition. 50 GB No Max. Forensic repository The disk space of the forensic records stored in the archive folder. 40 GB No Max. On endpoint client Type Description Default Setting Max Disk Space Endpoint client incident storage The disk space that each endpoint client should allocate for incident storage when the endpoint host is disconnected from the TRITON Management Server. 100 MB 100 MB Endpoint client log file The disk space of the log file viewed on the endpoint client. 16 MB 100 MB Endpoint client PreciseID fingerprint storage The disk space that each endpoint client should allocate for storing directory and SharePoint fingerprints. 50 MB 1,000 MB Modifying the disk space setting Follow the instructions below to modify the default disk-space settings for either archives, endpoint client incident storage, PreciseID fingerprint or forensic repositories. To modify disk space settings: 1. Access TRITON - Data Security and choose the Settings tab. 2. Depending on the disk space to modify, do the following: a. Archives: Select Settings > Configuration > System > Archive Storage. In the Maximum archive disk space field, modify the value. b. Forensics repository: Select Settings > Deployment > System Modules. In the list of modules, select the Forensics Repository entry. In the Maximum Disk Space field, set the value. c. Endpoint client (incident storage, log file and fingerprint storage): Select Settings > Configuration > System > Endpoint. In the section labeled Disk Space, modify the relevant disk-space value. 110 Define Product Name Variable Planning Data Security Deployment 3. Click OK. The disk space values are set and changes saved. 4. Click Deploy to deploy your settings. Distributing resources Websense Data Security supports multi-site, distributed deployments. You can have a local policy engine on the protector, for example, and distributed (primary and secondary) fingerprint repositories. You can have a management server in one location and one or more supplemental Data Security servers in other locations. You can utilize the crawlers on the Data Security servers alone to do your fingerprint and discovery scans, or you can install the crawler agent on additional servers to improve performance. These are just a few of the possibilities. Your network architecture and the geographical location of your offices determine how you will want to distribute your resources. See Most common deployments, page 112 for distributions our customers commonly use. Load balancing In a multi-component system, you can configure load-balancing by selecting Settings > Deployment > System Modules in TRITON - Data Security and then clicking the Load Balancing button at the top of the screen. Load balancing enables you to manage how each module sends its data to specified policy engines for analysis. This lets you distribute the load, but more important, it ensures that your vital email and HTTP performance is never harmed. For example, you can designate 1-2 dedicated servers to analyze inline HTTP traffic (where analysis latency is critical) and use another set of servers to analyze other channels. An agent or a protector service can be analyzed by all listed policy engines or it can be analyzed by specifically selected policy engines. (Note that protector services can be analyzed only by local or Windows-based policy engines.) In addition, you can choose which policy engine analyzes a specific agent or service of the protector. Note Websense recommends that you do not distribute the load to the TRITON management server. Define Book Name Variable 111 Planning Data Security Deployment The Load Balancing screen shows a list of items where each item represents a protector or agent. Click each item in the tree to define which policy engine it should be analyzed by. For further information on load balancing, refer to the TRITON - Data Security Help.

Planning a phased approach Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.7.x In this topic: Phase 1: Monitoring, page 121 Phase 2: Monitoring with notifications, page 122 Phase 3: Policy tuning, page 123 Phase 4: Enforcing, page 123 Phase 5: Discovery, page 123 Phase 6: Endpoint deployments, page 123 Next, you need to consider the tactics you can employ in protecting your data, how to configure policies, manage incidents and control access. To assess how to protect your data from compromise, we recommend using Define Product Name Variable in a multi-phased approach. Listed below is just one approach of many. Phase 1: Monitoring Start by monitoring data (auditing without blocking). The following steps usually constitute this phase (you may skip some of the steps if they are not relevant): Step A: Enable regulatory compliance, regional and industry-related predefined policies: This supplies a solid first stage of DLP (data loss prevention) deployment Define Book Name Variable 121 Planning Data Security Deployment Step B: Request custom policies from Websense: It will give you a good picture of what information is being sent out, by whom, to where and how Moving forward, you may identify that your enterprise has unique needs in terms of data identification that are not covered by predefined policies; for example, you may want to protect coupons that are issued or catalog numbers. To request a policy, please apply to Websense technical support. We will escalate your request and engage the research team. The usual turnaround is approximately 3 weeks (the research team will generally provide an estimated time to completion within 3 days of reviewing the request). Step C: Fingerprint data (can be also part of Phase 2): Data fingerprinting allows accurate and efficient data identification Database fingerprinting (PreciseID database technology): • • • • PreciseID database fingerprinting allows accurate and efficient detection of fingerprinted records coming from various sources: Database tables Database views CSV files Content policies can be flexibly defined on top of data sources. Detection rules can be configured as combinations of columns and thresholds for a given number of matches. Database fingerprinting can be used in conjunction with PreciseID patterns. While patterns identify a full range of data (for example, all credit cards), database fingerprinting can narrow down the detection only to credit cards of your enterprise customers. You may want to set higher severity on PreciseID database policies than on PreciseID patterns. Files, directory, and SharePoint fingerprinting (PreciseID files technology) • • • PreciseID files technology allows identification of unstructured data (free text) The data that we identify can already be in a different format (e.g., after PDF conversion), different context (excerpt of confidential document that was fingerprinted), and so on Advanced and efficient algorithms allow detecting fingerprints even on endpoints that have limited resources Phase 2: Monitoring with notifications At this stage, we recommend enabling email notifications to various people in the organization when a policy breach is discovered. The options are: Global security administrator (can be CISO) Data owners (specified for each policy) Senders (people that actually leak the information)—some enterprises prefer to use this option to educate users and watch the expected decrease in the amount of incidents over time in the Trends report. 122 Define Product Name Variable Planning Data Security Deployment Managers—direct managers of people that leak information (based on data in the directory server). Phase 3: Policy tuning (Phase 3 can be ongoing, in parallel to Phases 1 and 2.) Make sure that you keep the amount of incidents manageable and that all incidents are relevant. The options are: Disable policies that do not bring value to your enterprise Make sure the selected channels are relevant for application of policies Identify incidents that are authorized transactions and make appropriate changes in the authorization for specific policies (e.g., allowing sending specific information from certain sources to certain destinations) Change thresholds to avoid too many incidents from some policies Phase 3 is also good for making sure that you assign proper incident managers for various types of incidents, and that you create policy category groups in Data Security Manager and assign them to relevant incident managers. Phase 4: Enforcing This phase should begin after all the policies were successfully tuned and business owners, data owners and incident managers are trained and ready to handle the incidents: You can start with the SMTP channel only and then gradually move to HTTP enforcement as well. Or you could enforce FTP through ICAP and/or Websense Content Gateway integrations. Continue monitoring incidents and identify whether certain policies can be moved back to auditing only. (Consider this efficiency if you release the email regardless of incidents.) Encryption: As part of SMTP enforcement, you may want to integrate with encryption gateways. Websense can automatically route certain email transactions to be encrypted based on email content and/or policy definitions (actions). Phase 5: Discovery Again, this phase can start earlier, in parallel with other phases. Establish discovery tasks on sensitive corporate servers, databases, Exchange servers, and SharePoint sites that are widely accessed to ensure you know what sensitive information is located where, and who is allowed to access it. Phase 6: Endpoint deployments As explained with other phases, this phase can also be instituted earlier in the security process. Define Book Name Variable 123 Planning Data Security Deployment Make sure you are controlling data in use (removable media, clipboard operations, file access) by deploying Websense Data Endpoint in your enterprise: It will allow controlling data in use even if users are disconnected from network You may decide to install it in stealth (invisible) mode Local discovery will assist you in getting to the files that network discovery wouldn’t reach. (Essentially, local discovery is looking at the drives on a local machine, like a laptop, which can be disconnected from the network.) 124 Define Product Name Variable 6 Integrating Data Security with Existing Infrastructure Deployment and Installation Center | Data Security Solutions | Version 7.7.x Websense Data Security is an integral piece of your network architecture, and can be combined with your existing systems to ensure seamless Web and email protection. See the following for information about integrating Websense Data Security with existing systems. Working with existing email infrastructure, page 125 Working with Web proxies, page 130 Working with shared drives, page 144 Working with user directory servers, page 149 Working with Exchange servers, page 151 Working with IBM Lotus Domino and Lotus Notes, page 153 Working with existing email infrastructure Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.7.x In this topic: Using the SMTP agent, page 126 Using the protector, page 126 You can configure Websense Data Security within your existing email infrastructure to block and quarantine email that contravenes your policies. You can do this by connecting Websense Email Security Gateway, the SMTP agent, or the Websense protector to the network directly in the path of the traffic, enabling traffic to be not only monitored, but also blocked, quarantined, or even terminated before it reaches its destination. This section describes the SMTP agent and protector. For information on using Email Security Gateway, see Installing appliance-based Websense solutions, page 247. Deployment and Installation Center 125 Integrating Data Security with Existing Infrastructure Using the SMTP agent If you want the option to block email that breaches policy, the SMTP agent is the easiest deployment option to configure, monitor, and debug in a production email environment. Do the following to set up the SMTP agent within your email infrastructure for this purpose: 1. Run the Websense installer as described in Installing Data Security components, page 413. You can install the SMTP agent on a TRITON Management Server, supplemental Data Security server, or as a stand-alone agent on another Windows server machine equipped with Microsoft IIS. 2. To configure the SMTP agent, in TRITON - Data Security, select Settings > Deployment > System Modules. Select the SMTP agent. 3. Complete the fields as follows: In the General tab: • • In the SMTP Filter tab: • • If you want encrypted or flagged email to bypass analysis, select the Enable redirection gateway check box, then enter the redirection gateway IP and port. Specify the encryption and/or bypass flags to use. In the Advanced tab: • Select the Enable filtering on the following internal email domains check box. Enter the domain name or names to monitor and click Add. In the Encryption & Bypass tab: • Set the Mode to Blocking. Specify the action to take when an unspecified error occurs. Specify the footer to add to analyzed email, if any. Click OK to save all the above settings. 4. Select Main > Policy Management > DLP Policies. Select the policy rule that you wish to use for email management and click Edit. 5. Complete the fields as follows: Select Destinations, and check the Network Email box. Select Severity & Action, then select an action plan that includes notifications. 6. Click Deploy to activate the settings. 7. Configure your corporate email server to route email to the SMTP agent. (The agent becomes a MTA.) Using the protector There are 2 different SMTP modes: Monitoring mode (sometimes referred to as passive mode) Explicit Mail Transfer Agent (MTA) mode 126 Websense Data Security Solutions Integrating Data Security with Existing Infrastructure In monitoring mode, the protector monitors and analyzes SMTP traffic, but does not enable policies to block transactions. It is important that not all networks have permission to send email via the protector’s SMTP service, otherwise the protector can be used as a mail relay. To avoid this, you should limit the networks that send email via the protector. In explicit MTA mode, the protector acts as an MTA for your SMTP traffic and operates in protect mode. Protect mode allows you to block transactions that breach policy. This section contains the basic steps required to configure Data Security for these 2 topologies. For more information on deploying the protector inline, see Deploying the protector, page 325. Pre-installation checklist The figure below shows a common topology in which the protector is installed inline. The checklist in this section refers to the numbers in this figure. Before installation, check the following: Verify that the required hardware is available - check the latest release notes for the list of certified hardware. If inline mode is selected, verify that the protector contains a certified Silicom Network card (either Dual or Quad). Have the following ready before installation: Deployment and Installation Center 127 Integrating Data Security with Existing Infrastructure Valid IP addresses for the Data Security server and the protector management port in the Data Security LAN Make sure the following IP addresses are known prior to installation - they are required in order to complete the procedure: The complete list of internal networks (IP ranges and subnet masks) [1] If there is more than one site, the internal networks list should include the networks of all sites. A list of the mail server’s IP addresses (in all sites) [4] [6] The IP addresses of the mail relay, if one exists [5] [7] The IP address of the outbound gateway for the protector - this will typically be the internal leg of the firewall [2] The IP address of the inbound gateway for the protector - this will typically be the external leg of the backbone switch or router [6] The HELO string the protector will use when identifying itself. This is relevant for the SMTP channel only. If customized notifications will be displayed when content is blocked, these should be prepared beforehand. Setting up SMTP in monitoring mode 1. Power up the protector. 2. Run the Websense installer as described in Installing Data Security components, page 413.

Websense Content Gateway includes a Data Security policy engine on box and streamlines communication with the TRITON Management Server. If you have Websense Web Security Gateway or Web Security Gateway Anywhere, the Content Gateway proxy is included in the solution. Websense Data Security also supports the following Web proxies: 130 Websense Data Security Solutions Integrating Data Security with Existing Infrastructure Blue Coat Squid open source These proxies integrate with Websense Data Security over ICAP, an industry-standard protocol designed for off-loading specialized tasks from proxies. Blue Coat Web proxy Blue Coat provides protocol support for HTTP, HTTPS, and FTP. The integration solution described in this section is the recommended one. Other configurations can be implemented, but should be tested prior to deployment. Limitations The solution does not support FTP GET method for request modification. The solution does not support HTTP GET method for request modification. The solution is limited to scan files of 10MB. The system is capable of generating an error if a file exceeds that size. In the described deployment caching is not in effect (Blue Coat SG does not cache PUTs and POSTs). However, you should exercise care if a response mode configuration is used. Deployment This deployment recommendation describes a forward proxy: a Blue Coat SG appliance connected to a Websense protector using ICAP. The Blue Coat SG appliance serves as a proxy for all HTTP, HTTPS, and FTP transactions. It is configured with rules that route data to the Websense ICAP server. The Websense protector receives all traffic directed to it from the Blue Coat appliance for scanning, Deployment and Installation Center 131 Integrating Data Security with Existing Infrastructure The following diagram outlines the recommended deployment: The deployment solution can be used in 2 modes: Monitoring mode Enforcement mode You can change the mode as required. Enforcement mode In this mode, the Blue Coat SG appliance requires Websense Data Security to authorize each transaction before allowing the transactions to be posted or uploaded to 132 Websense Data Security Solutions Integrating Data Security with Existing Infrastructure their intended destination. This is the recommended mode of operation for the solution as it provides the most security. Monitoring mode In this mode, the transactions that are redirected by the Blue Coat SG appliance are analyzed by Websense Data Security, which can then generate audits for confidential information usage as well as generate notifications for administrators and information Deployment and Installation Center 133 Integrating Data Security with Existing Infrastructure owners. However, in monitoring mode, the Websense ICAP server universally responds to all redirected transactions with Allow. Network integration The solution consists of 3 components: Websense protector Websense TRITON Management Server Blue Coat SG appliance 134 Websense Data Security Solutions Integrating Data Security with Existing Infrastructure The Websense - Blue Coat ICAP integration component resides on the protector, and acts as a relay between the Blue Coat SG appliances and the TRITON Management Server as shown below: Configuring the Blue Coat integration System setup Refer to Installing Data Security Solutions, page 303, for instructions on installing Websense Data Security. Refer to relevant Blue Coat documentation for more information on installing the Blue Coat appliance. After connecting the systems, follow instructions to configure network parameters and other properties. Configuring Blue Coat The Blue Coat Proxy SG can be configured with its basic information. You will need several pieces of information to configure the Proxy SG: 1. IP address and netmask of the main interface 2. Default gateway IP address 3. DNS server IP address 4. Console user name and password 5. Enable password 6.

Complete the wizard as explained in the TRITON - Data Security Help. 152 Websense Data Security Solutions Integrating Data Security with Existing Infrastructure Working with IBM Lotus Domino and Lotus Notes Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: In this topic: Data Security, v7.7.x Before you begin, page 153 Getting started, page 153 Lotus Domino discovery, page 154 Lotus Domino fingerprinting, page 155 With Data Security, you can fingerprint and perform discovery on documents stored in an IBM Lotus Domino Data Management System (DMS). Data Security supports IBM Lotus Domino (Basic and Standard Editions) v7.x and 8.x on Windows Server 2003 or Windows Server 2008R2. Domino environments normally consist of one or more servers working together with data stored in Notes Storage Format (NSF) files. There are usually many NSFs on any given Domino server. NSF repositories contain documents and email messages, but Data Security performs discovery only on documents. These sections describe how to integrate your system with Data Security. Before you begin Before you begin, make sure that you: 1. Install Lotus Notes on the machine where you will install the Data Security crawler. This can be the machine where you plan to install the Data Security server software; or it can be a stand-alone machine where you plan to install the crawler agent. Important The crawler you will use for Domino fingerprinting and discovery must be on the same machine as Lotus Notes. Be sure that the installation is done for “Anyone who uses this computer.” 2. Log on to Lotus Notes and supply a user.id file and password. 3. Connect to the Lotus Domino server from the Lotus Notes client. This should be done by the user who will be installing the crawler. For best practice, do not run Lotus Notes on this machine again after the crawler is installed. Getting started To integrate Data Security with your Domino Server: Deployment and Installation Center 153 Integrating Data Security with Existing Infrastructure 1. Run the Data Security installation wizard on a machine with the Lotus Notes client. For best practice, do not run the Lotus Notes client on the machine on which the Data Security crawler is installed. 2. During installation, the installer detects the Notes client and displays the Lotus Domino Connections page. On this page: a. Select the check box labeled Use this machine to scan Lotus Domino servers. b. In the User ID file field, browse to one of the authorized users, then navigate to the user’s user.id file. Note Select a user that has permission to access all folders and Notes Storage Format (NSF) files of interest, otherwise certain items may not be scanned. c. In the Password field, enter the password for the authorized user. Note If you need to update the User ID and Password fields, run the installation wizard and select Modify. Lotus Domino discovery Lotus Domino discovery treats a document (body and attachments) as one unit. This way, a breach is reported even if the sensitive content is scattered in different parts of the document that individually would not cause an incident. To perform discovery on documents: 1. Log on to TRITON - Data Security, and create a discovery policy. To do so: a. Navigate to Main > Policy Management > Discovery Policies. b. Select Locate regulatory & compliance data or Create custom policy. c. Complete the steps in the wizard as described in the TRITON - Data Security Help. You can choose dictionary, RegEx, fingerprinting, or other classifiers as needed. 2. Create a Lotus Domino discovery task. To do so: a. Navigate to Main > Policy Management > Discovery Policies. b. Select Add network task > Lotus Domino Task. c. Complete the steps in the wizard as described in the TRITON - Data Security Help. 3. To deploy the policy and task to the Lotus Domino server, click Deploy. The Domino server will be crawled for your sensitive data at the next scheduled time. Incidents are reported under Main > Reporting > Discovery. 154 Websense Data Security Solutions Integrating Data Security with Existing Infrastructure Lotus Domino fingerprinting Lotus Domino fingerprinting treats the body of a document and each of its attachments as a separate item. This enables the system to show the full path down to the item inside a document that caused a breach. To fingerprint documents: 1. Log on to TRITON - Data Security, and create a Lotus Domino fingerprinting classifier. To do so: a. Navigate to Main > Policy Management > Content Classifiers > File Fingerprinting. b. Select New > Lotus Domino Fingerprinting. c. Complete the steps in the wizard as described in the TRITON - Data Security Help. 2. Create a Data Loss Prevention (DLP) policy using the following classifier: a. Navigate to Main > Policy Management > DLP Policies. b. Select Create custom policy. c. Complete the steps in the wizard as described in the TRITON - Data Security Help. Be sure to select the fingerprinting classifier on the Condition page. 3. To deploy the policy and classifier to the Lotus Domino server, click Deploy. The data on your Domino server will be fingerprinted at the next scheduled time. Incidents are reported under Main > Reporting > Data Loss Prevention. Deployment and Installation Center 155 Integrating Data Security with Existing Infrastructure 156 Websense Data Security Solutions 7 Scaling Data Security Deployment and Installation Center | Data Security Solutions | Version 7.7.x As your network (and the security needs of your network) grows, Websense Data Security can grow with it. Our software is architected for scalability, even for networks with massive traffic and complex topologies. The sections below address network growth issues such as recognizing when system loads demand system expansion, single and multi-site configuration and how to deal with the growth of the various information repositories. When does your system need to grow?, page 157 Adding modules to your deployment, page 160 When does your system need to grow? Deployment and Installation Center | Data Security Solutions | Version 7.7.x There are numerous triggers that might prompt your system expansion. Among them: Performance issues You may or may not be aware of performance issues affecting your system. If you are experiencing slow discovery or fingerprinting scans, for example, this could be an indication of an overworked crawler. You may benefit from an additional crawler or Data Security server. If user are experiencing slow Web or email transactions, you may benefit from an additional policy engine. Even if you are not aware of performance issues, your system resources may not be fully optimized. To see how your system is performing, open TRITON - Data Security and select Main > Status > System Health. You can expand each module and view statistics on the load, the number of transactions, the latency, and more. Before adding modules, try balancing the load between your existing Data Security servers (policy engines). To do this, go to Settings > Deployment > Deployment and Installation Center 157 Scaling Data Security System Modules, and click Load Balancing. Select a service and indicate which policy engine you’d like to assign to that service. Note Websense recommends that you do not distribute the load to the TRITON Management Server. The number of users grows In a typical small organization (1-500 users), you might only need a TRITON Management Server and a protector to monitor traffic. A larger organization (5002,500 users) might have a TRITON Management Server, a supplemental Data Security server, and a protector, with load balancing between the protector and supplemental server. (You cannot balance the load with the management server.) As your number of users grows, so does your need for a Data Security server. The number of transactions grows This is the most important requirement for determining your Data Security needs. Typically the number of transactions grows as your number of users grows. In monitoring mode, Websense recommends having 1 protector per 20,000 users. This calculation assumes: The protector is monitoring HTTP and SMTP There are 9 busy hours per day There are approximately 20 million transactions per day with a ratio of 15:1 HTTP:SMTP. (HTTP includes GETs and POSTs.) For more users, add an extra Data Security server and balance the load between the protector and the extra server. In blocking mode, Websense recommends 1 TRITON Management Server, 1 SMTP agent, and 1 V-Series appliance with Websense Content Gateway software. This calculation assumes: There are 9 busy hours per day There are approximately 15 million transactions per day with a ratio of 15:1 HTTP:SMTP. (HTTP includes GETs and POSTs.) 158 Websense Data Security Solutions Scaling Data Security For more users, add an extra Data Security server. Note that your transaction volume can grow even if your user base does not. If you anticipate adding a significant amount of traffic, you’d benefit from adding one or more Data Security servers. The number of endpoints grows If you subscribe to the Data Endpoint and you are adding endpoints to the system, you may need additional servers. A general rule of thumb is to add 1 Data Security server for every 30,000 endpoint clients. Moving your deployment from monitor to protect Enforcement requires more resources, particularly because load-balancing must be enforced between policy engines and SMTP agents. If you are moving from monitor to protect, you may benefit from an additional Data Security server. Moving from a single-site to multi-site configuration Websense Data Security supports multi-site, distributed deployments. You can have a local policy engine on the protector, for example, and distributed (primary and secondary) fingerprint repositories. You can have a management server in one location and one or more supplemental Data Security servers in other locations. You can utilize the crawlers on the Data Security servers alone to do your fingerprint and discovery scans, or you can install the crawler agent on additional servers to improve performance. These are just a few of the possibilities, and of course, all are scalable. See Most common deployments, page 112, for distributions our customers commonly use. Regardless, organizations having multiple geographical locations need a protector for each site. If you have multiple geographical locations with low latency between sites, you may need 2 protectors and 2 supplemental Data Security servers. Adding branch offices Each branch office requires a protector. If you are adding or acquiring a branch office, you should add a protector. Adding HTTP, SMTP and FTP egress points Deployment and Installation Center 159 Scaling Data Security If you are adding egress points to your network structure, you need to protectors to monitor or protect those egress points. The network grows (in GB) If you are performing network discovery, your network size greatly affects your requirements, as does the frequency of full versus differential scans. If your network is growing, you may require an additional crawler or Data Security server. Repositories such as forensics, fingerprint, policy database are reaching their maximum The Data Security software has some default settings for the disk-space requirements of its fingerprint and forensic repositories, but you can modify all of the values. Businesses with larger transaction volumes and numbers of users can adjust values significantly upward. (See Allocating disk space, page 109.) At some point, however, you may want to add another server to accommodate these repositories and increase your disk space. The forensics repository can get very large. It has a default setting of 40 GB. The archive has a default setting of 50 GB. Adding modules to your deployment Deployment and Installation Center | Data Security Solutions | Version 7.7.x If network and security requirements dictate that you need to add new agents or other modules to your deployment, go to the machine where you want to install them and run the Data Security installation wizard. When you install the module, you are asked to provide the FQDN of the TRITON management server and the credentials for a TRITON administrator with Data Security system modules permissions. When you do, the module is automatically registered with the management server. If you accept the default configuration, all you have to do is click Deploy in TRITON - Data Security (on the management server) to complete the process. If you want to customize the configurations, go into the System Modules screen and click the module to edit. Only a management user with system modules permissions can install new network elements. For information on adding and configuring modules, see Managing System Modules > Adding modules in the TRITON - Data Security Help. Value of additional policy engines Policy engines analyze transactions sent from various agents and protectors. The protector monitors network traffic and sends transactions to policy engines for analysis. The CPU load on the protector is much lighter than on a policy engine; 160 Websense Data Security Solutions Scaling Data Security therefore, when scaling up, you should add more policy engines (not protectors) and load-balance the analysis between them. Assessing the need for additional policy engines Check the number of transactions analyzed by the policy engine by selecting Main > Status > System Health and clicking on a policy engine. View the “Analysis status” chart for the policy engine. If there is red on the chart, this indicates a heavy load on the policy engine during the designated period. If you are in monitoring mode, a few red bars may not be an issue. The system will process these incidents during a less busy period. If you are in blocking mode, even one hour of red is undesirable. If you see this, you should perform load balancing and/or add a new Data Security server. Optimizing Try to avoid analysis of incoming traffic. If incoming is a must, try to limit it to certain domains. Never scan all networks; establish limits. Check the top policies and see if there are any false positives or unwanted/not needed policies a week or two after first deployment. If possible, make sure no spam SMTP mail is undergoing analysis. Deployment and Installation Center 161 Scaling Data Security 162 Websense Data Security Solutions 8 Email Security Gateway Deployment Deployment and Installation Center | Email Security Solutions | Version 7.7.x Applies to: Email Security Gateway and Email Security Gateway Anywhere v7.7.x Websense® Email Security Gateway provides maximum protection for email systems to prevent malicious threats from entering an organization’s network. Email Security provides comprehensive on-premises security hosted on a Websense V-Series™ appliance (V10000 G2 and V5000 G2). Email Security management functions reside on a separate Windows server in the TRITON™ Unified Security Center (TRITON Console). Each email message is analyzed by a robust set of virus, spam, and URL filters to prevent infected email from entering a network. Custom content filters allow Email Security to analyze messages based on administrator-specified message attribute conditions. Inbound, outbound, and internal email policies can be applied to user-defined sets of senders and recipients. A Websense Email Security Gateway Anywhere deployment adds support for a hybrid service pre-filtering capability “in the cloud,” which analyzes the characteristics of incoming email against a Websense database of known spam and viruses. Integration with TRITON - Data Security provides valuable data loss prevention (DLP) features to protect an organization’s sensitive data. Policies configured in the Data Security module can detect the presence of company data and block the transmission of that data via email. Data Security can also determine whether a message should be encrypted and pass the message to an encryption server. Logging and reporting capabilities allow an organization to view system and message status and generate reports of system and email traffic activity. Dashboard status charts (Main > Today and Main > History) are based on data collected by the Email Security logging and reporting functions. A Personal Email Manager facility allows authorized end users to release email messages that Email Security policy has blocked but that may be safe to deliver. End users can maintain personal Always Block and Always Permit lists of email addresses to simplify message delivery. User account management capabilities allow multiple Deployment and Installation Center 163 Email Security Gateway Deployment email account control and the delegation of email account management to other individuals. Email Security Gateway system requirements and deployment options are discussed in the following topics: System requirements, page 164 Single-appliance deployments, page 166 Multiple-appliance deployments, page 169 The sample diagrams in this guide show V-Series appliances running in Email Security only mode. See the following topics to view diagrams of an appliance running in dual Email Security Gateway/Web Security mode: Web Security and Email Security Gateway (Anywhere), page 254 Web Security Gateway (Anywhere) and Email Security Gateway (Anywhere) See the following topics for Email Security Gateway installation information: Installation steps for appliance-based solutions, page 263 Installing TRITON - Email Security, page 190 See the following topics for Email Security Gateway product upgrade information: Upgrading Email Security Gateway to v7.7, page 669 Upgrading the TRITON management server, page 574 System requirements Deployment and Installation Center | Email Security Solutions | Version 7.7.x Applies to: Email Security Gateway and Email Security Gateway Anywhere v7.7.x To view complete hardware, software, and Web browser requirements for TRITON - Email Security, see System requirements for this version, page 2, Every Email Security Gateway deployment includes the following components at a minimum: In the DMZ Websense V-Series appliance (V10000 G2 or V5000 G2), which includes the core Email Security functions and the Personal Email Manager end-user facility Email traffic volume in your network may determine which type of appliance you use and how many appliances your deployment needs. In the internal LAN 164 Email Security Gateway Email Security Gateway Deployment TRITON Unified Security Center management server with both Email Security and Data Security modules installed on a Windows Server® 2008 R2 machine Email Security Log Server Email Security Log Database (Microsoft® SQL Server® 2008, 2008 R2, or 2008 Express R2) Mail exchange server End-user machines Note All Email Security Gateway components must be synchronized by date and time for proper system communication. The network DMZ contains the devices that have direct contact with the Internet. This zone is a buffer between the Internet and the internal LAN. In our examples, the V-Series appliance and any router, switch, or load balancer adjacent to the firewall are located in the DMZ. Websense V-Series appliances The Websense V10000 G2 appliance provides the majority of Email Security Gateway functions. Incoming email flows from the email hybrid service (if enabled) to the Websense appliance and to the mail server. The Websense appliance also provides the Personal Email Manager facility for end users to manage quarantined email. Email Security Gateway can be installed and deployed on a dual-mode V10000 G2 appliance with either Web Security or Web Security Gateway. The Websense V5000 G2 appliance also provides the majority of Email Security Gateway functions and includes the Personal Email Manager end-user facility. The V5000 appliance can also be configured in dual mode with Web Security and Email Security Gateway. TRITON management server The TRITON management server hosts the TRITON Unified Security Center (TRITON Console). This machine includes TRITON Infrastructure and any installed TRITON Console management modules. In an Email Security Gateway deployment, the TRITON management server includes both the Email Security Gateway and Data Security modules. Email Security Log Server The TRITON management server often includes the Email Security Log Server component. The log server passes information to the SQL Server reporting database (Email Security Log Database) for use in generating dashboard charts and reports. Deployment and Installation Center 165 Email Security Gateway Deployment During installation, a user configures certain aspects of log server operation, including how log server interacts with Email Security Gateway. These settings can be changed when needed via the Email Security Log Server Configuration utility. Other details about log server operation are configured in this utility as well. The utility is installed on the same machine as log server. Email Security Log Database (Microsoft SQL Server) Microsoft SQL Server handles the system and message log database and stores some Email Security configuration settings. SQL Server may be installed on the TRITON management server (SQL Server Express R2 only) or on a dedicated server. For optimal performance, Websense recommends that a full SQL Server (2008 or 2008 R2) be installed on a separate machine. For information about database systems in Websense products, see Administering Websense Databases. Personal Email Manager The Email Security appliance is the portal for Personal Email Manager end users who are authorized to manage their own blocked mail. Personal Email Manager end-user options are configured in the Email Security management server interface (Settings > Personal Email). A Personal Email Manager administrators can determine: Which end users can access the Personal Email Manager utility What the blocked email notification message contains Which end users are allowed to manage personal Always Block and Always Permit lists Whether a user can manage multiple email accounts Whether a user can delegate email account management responsibilities to another individual (for end users in an LDAP-based user directory, this function can be enabled on the Add or Edit User Directory page) Single-appliance deployments Deployment and Installation Center | Email Security Solutions | Version 7.7.x Applies to: Email Security Gateway and Email Security Gateway Anywhere, v7.7.x In this topic 166 Email Security Gateway Email Security Gateway single appliance, page 167 Email Security Gateway Anywhere single appliance, page 168 Email Security Gateway Deployment Email Security Gateway single appliance A simple Email Security Gateway deployment uses a single V-Series appliance (either a V10000 G2 or V5000 G2 machine). In this installation, all email analysis occurs in the Email Security Gateway on-premises component using a robust collection of spam, virus, and URL filtering tools (Main > Policy Management > Filters). The Personal Email Manager facility on the appliance allows end users to manage blocked messages. Data Security data loss prevention (DLP) policies analyze email to ensure acceptable usage policies are enforced and sensitive company data is not lost. DLP policies are enabled in the Email Security module (Main > Policy Management > Policies) but are configured in the Data Security module. Deployment and Installation Center 167 Email Security Gateway Deployment See the TRITON - Data Security Help for details about DLP policy settings. See the following TRITON - Email Security Help topics for information about Email Security filter and policy tools: Creating and configuring email filters Creating and configuring email policies Email Security Gateway Anywhere single appliance A simple Email Security Gateway Anywhere deployment uses a single V-Series appliance (either a V10000 G2 or V5000 G2 machine). Websense Email Security Gateway Anywhere offers a comprehensive email security solution that combines the on-premises functions described earlier with hybrid (in-the-cloud) email analysis to manage an organization’s email traffic. 168 Email Security Gateway Email Security Gateway Deployment The hybrid service provides an extra layer of email analysis, stopping spam, virus, phishing, and other malware before they reach the network, potentially reducing email bandwidth and storage requirements. The hybrid service can be used to send outbound email to an encryption server before delivery to its recipient. The hybrid service prevents malicious email traffic from entering a company’s network by: Dropping a connection request based on the reputation of the IP address of the request Comparing the characteristics of inbound email against a Websense database of known spam and viruses, and blocking any message that matches a database entry The hybrid service may also share spam and virus detection information by writing extended headers in the mail it sends to Email Security Gateway. The additional header information includes a spam/virus detection “score,” which Email Security then uses to determine message disposition. This function can enhance Email Security system performance. The Email Security Gateway Anywhere subscription must include the email hybrid service, and the hybrid service must be enabled and properly registered before hybrid service analysis can begin. Register for the hybrid service in the Email Security Gateway management interface (Settings > Hybrid Service > Hybrid Configuration). The Hybrid Service Log contains records of the email messages that are blocked by the hybrid service. After the hybrid service is registered and enabled, users can view the log at Main > Status > Logs by clicking the Hybrid Service tab. See the TRITON - Email Security Help for details on all hybrid service options: Registering the email hybrid service Configuring the Hybrid Service Log Viewing the Hybrid Service Log Multiple-appliance deployments Deployment and Installation Center | Email Security Solutions | Version 7.7.x Applies to: Email Security Gateway and Email Security Gateway Anywhere, v7.7.x In this topic Email Security Gateway Anywhere appliance cluster, page 170 Multiple standalone appliances, page 172 Multiple V-Series appliance deployments can be implemented when message volume warrants having greater processing capacity. When the deployed appliances are all in standalone mode, the appliances can be a mix of either V10000 G2 or V5000 G2 Deployment and Installation Center 169 Email Security Gateway Deployment machines. In an appliance cluster, however, all the machines must be either V10000 G2 or V5000 G2 machines. A cluster cannot contain a mix of appliance platforms. Email Security Gateway Anywhere appliance cluster Multiple V-Series appliances are configured in Email Security Gateway as a cluster for this deployment scenario. Appliances in a cluster must all be either V10000 G2 machines or V5000 G2 machines. A cluster cannot contain a mix of different appliance platforms. This Email Security Gateway Anywhere environment includes the Email Security hybrid service “in the cloud” filtering. See Email Security Gateway Anywhere single appliance, page 168, for information about the email hybrid service. You may want to use a third-party load balancer with an appliance cluster, to distribute email traffic among your appliances. Appliances in a cluster all have the same configuration settings, which can streamline a load balancing implementation. Personal Email Manager traffic load balancing may be accomplished via cluster configuration. After a cluster is created, designate the Personal Email Manager access point in Settings > Personal Email > Notification Message, in the Personal Email Manager Portal section. Personal Email Manager traffic is routed to this designated IP address. This appliance then passes the traffic on to other appliances in the cluster via the round robin forwarding mechanism. To create a cluster, add an appliance to the Email Security appliances list on the Settings > General > Email Appliances page, then configure these appliances in a 170 Email Security Gateway Email Security Gateway Deployment cluster on the Settings > General > Cluster Mode page. See the TRITON - Email Security Help for details. A primary appliance in a cluster may have up to 7 secondary (or auxiliary) appliances. Configuration settings for any cluster appliance are managed only on the primary appliance Email Appliances page (Settings > General > Email Appliances). Cluster appliances must all be running in the same security mode (Email Security only mode or dual Email Security/Web Security mode). The Email Security Gateway management server (TRITON Console) and all cluster appliance versions must all match for cluster communication to work properly. In order to protect the messages stored in Email Security queues, appliances added to a cluster must have the same message queue configuration as the other cluster appliances. For example, an administrator-created queue on appliance B must be configured on primary cluster appliance A before appliance B is added to the cluster. Deployment and Installation Center 171 Email Security Gateway Deployment Message queue records may be lost if this step is not performed before cluster creation. Multiple standalone appliances A multiple standalone appliance deployment might be useful if each appliance must have different configuration settings. Two standalone scenarios are described in this section: Using DNS round robin, page 172 Using domain-based routing, page 173 These Email Security Gateway Anywhere environments include the Email Security hybrid service “in the cloud” filtering. See Email Security Gateway Anywhere single appliance, page 168, for information about the email hybrid service. Using DNS round robin Email traffic distribution among multiple standalone appliances can be accomplished by using the domain name system (DNS) round robin method for distributing load. With Email Security hybrid service configured and running, set up the round robin system as follows: 1. Enter the SMTP server domain in the Delivery Route page of the hybrid service configuration wizard used for registering Email Security Gateway with the hybrid service (Settings > Hybrid Service > Hybrid Configuration). 2. Register the IP addresses of the appliances you want subject to the round robin method in the SMTP domain. If hybrid service is not enabled, you need to modify your MX records to allow round robin load balancing. Ask your DNS manager (usually your Internet service provider) 172 Email Security Gateway Email Security Gateway Deployment to replace your current MX records with new ones for load balancing that have a preference value equal to your current records. Using domain-based routing You can configure domain-based delivery routes so that messages sent to recipients in specified domains are delivered to a particular appliance. Configure the domain groups for which you want to define delivery routes in the Settings > Users > Domain Groups > Add Domain Groups page. See the TRITON - Email Security Help for information about adding or editing domain groups: Managing domain groups Configuring delivery routes Deployment and Installation Center 173 Email Security Gateway Deployment To set up a domain-based delivery route on the Settings > Inbound/Outbound > Mail Routing page: 1. Click Add in the Domain-based Routes section to open the Add Domain-based Route page. 2. Enter a name for your route in the Name field. 3. Select an order number from the Route order drop-down list to determine the route’s scanning order. 4. Select a destination domain from the pre-defined domains in the Domain group drop-down list. Default is Protected Domain. Information about the selected domain group appears in the Domain details box. If you want to add a new domain group to the list, navigate to Settings > Users > Domain Groups and click Add. If you want to edit your selected domain group, click Edit to open the Edit Domain Group page. Important The Protected Domain group defined in the Settings > Users > Domain Groups page should not be used to configure Email Security Gateway delivery routes if you need to define domain-based delivery routes via multiple SMTP servers. Create domain groups that contain subsets of the Protected Domain group for mail routing purposes. 5. Select the SMTP server IP address delivery option and enter the following information: a. Enter the SMTP server IP address or host name and port. b. Mark the check box to enable MX lookup. c. Click the right arrow to add the SMTP server information to the SMTP Server List. Mail for that domain group is delivered to the specified SMTP server for routing to the domain address. 174 Email Security Gateway 9 Installation Overview: TRITON Enterprise Deployment and Installation Center | Web, Data, and Email Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Deployment, page 175 Installation, page 179 Initial configuration, page 180 Data Security, v7.7.x Email Security Gateway and Email Security Gateway Anywhere, v7.7.x This section provides an overview of TRITON Enterprise deployment and installation activities. Deployment Websense TRITON Enterprise includes Web Security Gateway Anywhere, Data Security, and Email Security Gateway Anywhere. Core Email Security Gateway Anywhere components can reside only on Websense appliances. Web Security Gateway Anywhere may be deployed on Websense appliances, dedicated Windows and Linux servers, or a combination of both. Data Security is located on Windows servers and elsewhere in the network. The TRITON management interface for Web, Email, and Data Security, resides on a separate Windows server. Deployment and Installation Center 175 Installation Overview: TRITON Enterprise The following illustration is a high-level diagram of a basic V10000 G2-based deployment of TRITON Enterprise. 176 Websense TRITON Enterprise Installation Overview: TRITON Enterprise Remote office and off-site users You can use the hybrid Web service to provide Web security for small remote offices. This is accomplished by designating a remote office as a hybrid filtered location. See Initial configuration, page 180, for more information. Either the hybrid service or Websense remote filtering software can provide Web filtering for off-site users (e.g., telecommuters or traveling personnel). To use the hybrid service, a PAC file or Websense Web Endpoint is installed on the user’s machine. This directs Web browsing to be filtered through the hybrid service according to policies in place. To use remote filtering software, Remote Filtering Server is installed in your network and Remote Filtering Client is installed on user machines. See Deploying Remote Filtering Server and Client. Hybrid services If your subscription includes Web Security Gateway Anywhere and Email Security Gateway Anywhere: The cloud-based (SaaS) hybrid Web service can be used to provide Internet security for remote offices and off-site users. The cloud-based email hybrid service provides an extra layer of email scanning, stopping spam, virus, phishing, and other malware attacks before they reach your network and possibly reducing email bandwidth and storage requirements. You can also use the hybrid service to encrypt outbound email before delivery to its recipient. Websense Appliances Websense V-Series appliances may be used to deploy core Web and Email Security Gateway functionality. The Content Gateway proxy on the appliance manages Web traffic. Incoming email flows from the email hybrid service (if enabled) to the Websense appliance and to your mail server. The Websense appliance also provides the Personal Email Manager facility for end users to manage quarantined email. Data Security Protector The protector is a Linux-based soft-appliance, providing monitoring and blocking capabilities, preventing data loss and leaks of sensitive information. Using PreciseID technology, the protector can be configured to accurately monitor sensitive information-in-transit on any port. Deployment and Installation Center 177 Installation Overview: TRITON Enterprise Components that may not be installed on Websense appliances TRITON management server The TRITON management server is the Windows machine on which TRITON Unified Security Center (TRITON Console) is installed. The TRITON Console is the management and reporting interface for Websense Web, Data, and Email Security solutions. Data Security Management Server and, typically, Crawler also reside on the TRITON management server machine to providing key Data Security functions, including Web and email DLP (data loss prevention) features. Linking Service also usually resides on the management server. Web Security and Email Security Log Server A separate Windows machine hosts Web Security Log Server and Email Security Log Server. These services receive information about Web Security and Email Security activity and process it into their respective Log Database. Optional Web Security components Sync Service and transparent identification agents (DC Agent, Logon Agent, eDirectory Agent, and RADIUS Agent) may not reside on V-Series appliances. Also, you can install additional instances of several Web Security filtering components on Windows or Linux servers, if needed.

Archiving lets you manage the size of your incident database and optimize performance. Backup lets you safeguard your policies, forensics, configuration, data, fingerprints, encryption keys, and more. If you do not plan to archive incidents or perform system backup and restore, you do not need to fill out this screen. Before proceeding, create a folder in a location that both the database and TRITON management server can access. (The folder must exist before you click Next.) On average, this folder will hold 10 GB of data, so choose a location that can accommodate this. On the Temporary Folder Location screen, complete the fields as follows: Enable incident archiving and system backup: Check this box if you plan to archive old or aging incidents and perform system backup or restore. This box does not appear when you run the installer in Modify mode and perform a disaster recovery restore operation. 188 Websense TRITON Enterprise Installation Overview: TRITON Enterprise From SQL Server: Enter the path that the SQL Server should use to access the temporary folder. For best practice, it should be a remote UNC path, but local and shared network paths are supported. For example: c:\folder or \\10.2.1.1.\folder. Make sure the account used to run SQL has write access to this folder. From TRITON Management Server: Enter the UNC path the management server should use to access the temporary folder. For example: \\10.2.1.1.\folder. Enter a user name and password for a user who is authorized to access this location. Important For all 7.7.x versions, the account used to access the SQL Server must have BACKUP DATABASE permissions to communicate with the installer. If it does not, an error results when you click Next. To grant this permission, issue the following T-SQL commands on the SQL Server instance: USE master GRANT BACKUP DATABASE TO <user> GO After installation of Data Security components, you can revoke this permission: USE master REVOKE BACKUP DATABASE TO <user> GO 8.

Installing TRITON - Email Security Deployment and Installation Center | Email Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, and Web Security Gateway (Anywhere), v7.7.x Data Security, v7.7.x Email Security Gateway (Anywhere), v7.7.x Follow these instructions to install the Email Security module of the TRITON Unified Security Center. In addition to the Email Security module (also referred to as TRITON - Email Security), you will be given the option to install Email Security Log Server on this machine. 1. It is assumed you have reached this point by starting a TRITON Unified Security Center installation and selecting the Email Security module. If not, see Creating a TRITON Management Server, page 180. 2. Once the Email Security Installer is launched, the Introduction screen appears, click Next to begin Email Security installation. 3. On the Select Components screen, choose whether to install Email Security Log Server on this machine and then click Next. TRITON - Email Security (i.e, the Email Security module of the TRITON Unified Security Center) will be installed automatically. You cannot deselect it. Note If you do not see TRITON - Email Security on this screen, TRITON Infrastructure was not detected by the Email Security Installer. TRITON Infrastructure must be installed already to be able to install TRITON - Email Security. Email Security Log Server is selected for installation by default. To install Email Security Log Server, SQL Server or SQL Server Express must already be installed and running in your network (see System requirements for this version, page 2, for supported versions of SQL Server). If you chose to install SQL Server Express during TRITON Infrastructure installation, then it is already installed on this machine. If you choose to install Email Security Log Server, the Email Security Log Server Configuration utility is also installed. This utility can be accessed by selecting 190 Websense TRITON Enterprise Installation Overview: TRITON Enterprise Start > All Programs > Websense > Email Security > Email Security Log Server Configuration. You can install Email Security Log Server on another machine; it is not required to be installed on the same machine as TRITON - Email Security. To install log server on a different machine, deselect the Email Security Log Server option here (in the Select Components screen) and complete Email Security installation. Then run TRITON Unified Security Setup on the machine on which you want to install Email Security Log Server. Perform a custom installation of Email Security components (see Installing Email Security components, page 414). 4. On the Email Security Database screen, specify the IP address or IP address and instance name (format: IP address\instance) for the Email Security database. You may specify whether the connection to the database should be encrypted. Please note the following issues associated with using this encryption feature: You must have imported a trusted certificate to the Log Server machine in order to use the encryption option. See your database documentation for information about importing a trusted certificate. The Bulk Copy Program (BCP) option for inserting records into the Log Database in batches cannot be used. Not using the batch method may affect Log Database performance. The connection from the Email Security module on the TRITON Console to the V-Series appliance cannot be encrypted. If you enable encryption for Log Database, you must disable the SQL Server force encryption feature. Designate the login type for the database, either Windows authentication or sa account. 5. On the Email Security Database File Location screen, specify where Email Security database files should be located and then click Next. This screen appears only if you chose to install Email Security Log Server in addition to TRITON - Email Security. A default location for the Log Database is automatically shown. Information about the location of the database engine and connection credentials were entered when TRITON Infrastructure was installed on this machine. The Email Security Installer reads this information from configuration files created by TRITON Infrastructure Setup. It is a best practice to use the default location. However, if you want to create the Log Database in a different location (or if you already have a Log Database in a different location), enter the path to the database files. The path entered here is understood to refer to the machine on which the database engine is located. The path entered must specify a directory that already exists. 6. On the Email Security Gateway screen specify the Email Security Gateway appliance to be managed by this installation of the TRITON Unified Security Center and then click Next. Enter the IP address of the C interface of the Email Security Gateway appliance. You must specify an IP address only. Do not use a fully-qualified domain name (FQDN). Deployment and Installation Center 191 Installation Overview: TRITON Enterprise When you click Next, communication with the specified appliance will be verified. Communication may be unsuccessful if: Subscription key has already been applied to the appliance (typically meaning another installation of TRITON Unified Security Center has been used to manage the appliance). The subscription key must be reset on the appliance. Version of software to be installed does not match the version of the appliance. Verify whether the versions match. Specified appliance is a secondary appliance in a cluster. Specify the primary appliance in the cluster or a non-clustered appliance. The appliance cannot connect to the specified database server (specified during product installation). Firewall is blocking communication to the appliance on port 6671. Make sure any local firewall allows outbound communication on port 6671. Appliance E interface has not been correctly configured in the Appliance Manager. 7. On the Installation Folder screen, specify the location to which you want to install Email Security components and then click Next. To select a location different than the default, use the Browse button. Each component (TRITON - Email Security and/or Email Security Log Server) will be installed in its own folder under the parent folder you specify here. 8. On the Pre-Installation Summary screen, review the components to be installed. If they are correct, click Install. Click Back to return to any screen on which you want to modify settings. 9. The Installing Websense Email Security screen appears, as components are being installed. 10. Wait until the Installation Complete screen appears, and then click Done. 11.

For information about multiple instances or combinations of transparent identification agents, see Combining transparent identification agents, page 49. Use Logon Agent to identify users logging on to local machines: This option installs Websense Logon Agent on this machine. Logon Agent identifies users as they log onto Windows domains. Logon Agent is for use with Windows-based client machines on a network that uses Active Directory or Windows NT Directory. To use Logon Agent, you must modify the Group Policy on domain controllers so it launches a logon application (LogonApp.exe) as part of the logon script. Client machines must use NTLM (v1 or v2) when authenticating users. See the Using Logon Agent for Transparent User Identification technical paper. Note Do not use Logon Agent in a network that already includes eDirectory Agent. Use eDirectory Agent to identify users logging on via Novell eDirectory Server: This option installs eDirectory Agent on this machine. Use this agent for a network using Novell eDirectory. eDirectory Agent queries the eDirectory Server at preset intervals to identify users currently logged on. Note Do not use eDirectory Agent in a network that already includes DC Agent or Logon Agent. Do not install a transparent identification agent now: Select this option if • • • Websense software will be integrated with Content Gateway or a thirdparty product that provides user authentication. You plan to install a transparent identification agent on another machine. You do not want different filtering policies applied to users or groups. Deployment and Installation Center 213 Installing Web Security Components on Linux • You want users to be prompted for logon information when they open a browser to access the Internet.

Deployment and Installation Center 217 Installing Web Security Components on Linux 218 Websense Web Security Solutions 12 Installing Websense Content Gateway Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: In this topic Web Security Gateway and Web Security Gateway Anywhere, v7.7.x Deployment Installation Online Help Websense Content Gateway (Content Gateway) is a Linux-based, high-performance Web proxy and cache that provides real-time content analysis and Web site classification to protect clients from malicious Web content while enabling access to safe content. Content Gateway offers: Categorization of dynamic Web sites Categorization of new and unclassified sites HTTPS content analysis Enterprise proxy caching capabilities Note In a Websense-appliance-based deployment, when Web Security Gateway (Anywhere) is configured, Content Gateway is already installed. In a software-based deployment, Content Gateway is a required part of Websense Web Security Gateway and Web Security Gateway Anywhere. Content Gateway must be installed on a Linux machine. The machine should be dedicated to running Content Gateway. Websense Web Security Gateway and Web Security Gateway Anywhere subscribers get the following features, in addition to the standard Websense Web Security features: Security analysis that inspects incoming Web pages to immediately block malicious content, such as phishing, malware, and viruses. Deployment and Installation Center 219 Installing Websense Content Gateway Advanced file analysis that applies both advanced detection techniques and traditional antivirus scanning to discover and block infected and malicious files users are attempting to download. See the TRITON - Web Security Help and read the section titled Scanning Options. When installed as part of Websense Web Security Gateway Anywhere, Content Gateway also works with Websense Data Security Management Server to prevent data loss over Web channels. For more information, see Installation overview: Web Security Gateway Anywhere, page 200. Content Gateway can be used as an explicit or transparent proxy. In an explicit proxy deployment, client applications, typically browsers, must be configured to send requests to Content Gateway. In a transparent proxy deployment, client requests are intercepted and redirected to Content Gateway by an external network device (required). If you enable SSL Manager, the content on HTTPS pages is decrypted, examined for security issues, and, if appropriate, re-encrypted and forwarded to the destination. When you run Content Gateway with Websense Data Security to inspect HTTPS and FTP traffic, you must enable the SSL Manager feature. See Content Gateway Manager Help for information on SSL Manager.

You will need them when installing Content Gateway. Note Be sure hostname and DNS are configured before installing your Websense products (see System requirements for Websense Content Gateway. In addition, synchronize the time on the filtering-software and Content Gateway machines. It is a best practice to use a Network Time Protocol (NTP) server. Preparing to install Websense Content Gateway Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Security Gateway and Web Security Gateway Anywhere, v7.7.x In this topic Downloading the installer Internet connectivity Security of the Content Gateway machine Explicit or Transparent Proxy System requirements for Websense Content Gateway Hostname and DNS configuration for Content Gateway Preparing a cache disk for use by Websense Content Gateway Preparing for a clustered deployment of Websense Content Gateway Before installing Websense Content Gateway (Content Gateway) on a machine, perform the following tasks and consider the following issues. 222 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway Downloading the installer 1. Download the WebsenseCG77Setup_Lnx.tar.gz installer tar archive, from mywebsense.com to a temporary directory. For version 7.7.3 the name is: WebsenseCG773Setup_Lnx.tar.gz 2. Create a directory for the tar archive, and then move the archive to the new directory. For example: mkdir wcg_v77 mv <installer tar archive> wcg_v77 3. Change to the directory you created in Step 2. cd wcg_v77 4. Unpack the tar archive: tar -xvzf <installer tar archive> Internet connectivity It is recommended that the Content Gateway machine have Internet connectivity before starting the installation procedure. The software will install without Internet connectivity, but analytic database updates cannot be performed until Internet connectivity is available. Security of the Content Gateway machine Consider these security issues prior to installing Content Gateway: Physical security Root permissions Ports Physical security Physical access to the system can be a security risk. Unauthorized users could gain access to the file system, and under more extreme circumstances, examine traffic passing through Content Gateway. It is strongly recommended that the Content Gateway server be locked in an IT closet and that a BIOS password be enabled. Root permissions Ensure that root permissions are restricted to a select few persons. This important restriction helps preclude unauthorized access to the Websense Content Gateway file system. Deployment and Installation Center 223 Installing Websense Content Gateway Ports For a list of default ports, see Content Gateway ports. They must be open to support the full set of Websense Web Security Gateway features. Note If you customized any ports that Websense software uses for communication, replace the default port with the custom port you implemented. Restrict inbound traffic to as few other ports as possible on the Websense Content Gateway server. In addition, if your subscription does not include certain features, you can restrict inbound traffic to the unneeded ports. For example, if your subscription does not include Websense Data Security, you may choose to restrict inbound traffic to those ports related to Websense Data Security. IPTables Firewall If your server is running the Linux IPTables firewall, you must configure the rules in a way that enables Content Gateway to operate effectively. See the IPTables for Content Gateway article in the Websense Technical Library. Explicit or Transparent Proxy Content Gateway can be used as an explicit or transparent proxy. This section contains the following topics: Explicit proxy Configuring client browsers for explicit proxy Configuring Internet Explorer 8.0 and later for explicit proxy Configuring Firefox 5.x for explicit proxy Explicit proxy Explicit proxy deployment requires directly pointing client Web browsers (And other client applications) to Content Gateway for HTTP, and optionally, HTTPS and FTP traffic. This is accomplished by a using a PAC file, WPAD, or by having the user edit browser settings to point to Content Gateway. One issue to consider with explicit deployment is that a user can point his or her browser to another destination to bypass Content Gateway. You can address this by setting and propagating browser configuration in your organization through Group Policy, a Windows Server feature. For more information about Group Policy, search the Microsoft TechNet Web site at http://technet.microsoft.com. An additional way to mitigate the risk of users bypassing Content Gateway is the use of corporate outbound firewall rules. 224 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway Multiple proxies can provide for redundancy using Virtual Router Redundancy Protocol (VRRP). Using a single IP address, requests are sent to an alternate proxy in the event of failure. VRRP is not invoked until there is a failure with one of the proxies. See RFC 3768 for information on VRRP. Configuring client browsers for explicit proxy For explicit proxy deployments, you must configure each client browser to send Internet requests to Content Gateway, over the ports that Content Gateway uses for the associated protocol. The default proxy port in Content Gateway for both HTTP and HTTPS traffic is 8080. The default port for FTP is 2121. Use the instructions below to configure client browsers manually. Alternatively, use a PAC or WPAD file to configure client browsers. Note The instructions below are for the most common client browsers. For other client browsers refer to the browser’s documentation for instructions on manual explicit proxy configuration. Configuring Internet Explorer 8.0 and later for explicit proxy 1. In Internet Explorer, select Tools > Internet Options > Connections > LAN Settings. 2. Select Use a proxy server for your LAN. 3. Click Advanced. 4. For HTTP, enter the Content Gateway IP address and specify port 8080. 5. For Secure, enter the Content Gateway IP address and specify port 8080. 6. Clear Use the same proxy server for all protocols. 7. Click OK to close each screen in this dialog box. Configuring Firefox 5.x for explicit proxy 1. In Firefox, select Tools > Options > Advanced, and then select the Network tab. 2. Select Settings. 3. Select Manual proxy configuration. 4. For HTTP Proxy, enter the Content Gateway IP address and specify port 8080. 5. For SSL Proxy, enter the Content Gateway IP address and specify port 8080. 6. Click OK to close each screen in this dialog box. Transparent proxy In transparent proxy deployments, client requests are intercepted and redirected to Content Gateway, without client involvement, via a WCCPv2-enabled router or Layer Deployment and Installation Center 225 Installing Websense Content Gateway 4 switch in your network. In a multiple-proxy (cluster) deployment, a WCCP v2-enabled router also supports load distribution among proxies. See Content Gateway Manager Help for additional information on configuring a WCCPv2-enabled router or a Layer 4 switch, and about the ARM (Adaptive Redirection Module).

The caching disk: – Should be at least 2 GB and no more than 147 GB – Must be a raw disk, not a mounted file system – Must be dedicated – Must not be part of a software RAID – Should be, for best performance, a 10K RPM SAS disk on a controller that has at least 64 MB of write-through cache Network Interfaces 2 226 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway To support transparent proxy deployments Router —or— Layer 4 switch Must support WCCP v2. A Cisco router must run IOS 12.2 or later. Client machines, the destination Web server, and Content Gateway must reside on different subnets. You may use a Layer 4 switch rather than a router. To support WCCP, a Cisco switch requires the EMI or IP services image of the 12.2SE IOS release (or later). Websense Content Gateway must be Layer 2 adjacent to the switch. The switch must be able to rewrite the destination MAC address of frames traversing the switch. The switch must be able to match traffic based on the layer 4 protocol port (i.e., TCP port 80). Software Content Gateway version 7.7.3 is certified on all of the Red Hat Enterprise Linux versions that 7.7.0 is certified on, plus: Update 3, 64-bit, Basic Server Content Gateway version 7.7.0 is certified on: Red Hat Enterprise Linux, 6 series, updates 0, 1, and 2, 64-bit, Basic Server Red Hat Enterprise Linux, 5 series, updates 3, 4 and 5, base or Advanced Platform, 32-bit only The corresponding CentOS versions (CentOS version numbers have a one-to-one correspondence with Red Hat Enterprise Linux version numbers). Although not certified, Websense, Inc. provides “best effort” support for newer versions of Red Hat Enterprise Linux. Under “best effort” support, Websense Technical Support makes a best effort to troubleshoot cases in standard fashion unless the issue is deemed a Red Hat Enterprise Linux-specific issue, at which point you must contact Red Hat directly for assistance. Only kernels shipped with the above Linux versions are supported by Websense Content Gateway. Visit www.redhat.com for kernel information. To display the kernel version installed on your system, enter the command: /bin/uname -r For more information on installing on Red Hat Enterprise Linux, see Requirements for Red Hat Enterprise Linux. Deployment and Installation Center 227 Installing Websense Content Gateway Websense Web filtering components Versions must match. When version 7.7.0 is used, TRITON – Web Security must be version 7.7.0. When version 7.7.3 is used, TRITON – Web Security must be version 7.7.3. Important Websense filtering software must be installed prior to Content Gateway. When the filtering software is installed, Websense Content Gateway must be specified as the integration product. See Installation overview: Web Security Gateway, page 197, Installing via the Web Security All option, page 204, or Installation overview: Web Security Gateway Anywhere, page 200,. Integration with Websense Data Security The version must match other installed components. Version 7.7.0 or 7.7.3 (to take advantage of the co-located Data Security policy engine) The order of installation does not matter. Websense Data Security may be installed before or after Content Gateway. Any version can be used via the ICAP interface. See Content Gateway Manager Help for configuration instructions. Web browsers Content Gateway is configured and maintained with a Web-based user interface called the Content Gateway Manager. Content Gateway Manager supports the following Web browsers: Internet Explorer 8 and 9 Mozilla Firefox 5 and later Google Chrome 13 and later Note The browser restrictions mentioned above apply only to the Content Gateway Manager and not to client browsers proxied by Content Gateway. Hostname and DNS configuration for Content Gateway Configure a hostname for the Content Gateway machine and also configure DNS name resolution. Complete these steps on the machine on which you will install Content Gateway. 228 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway 1. Configure the hostname: hostname <hostname> where <hostname> is the name you are assigning this machine. Important The hostname must be 15 characters or less. 2. Update the HOSTNAME entry in the /etc/sysconfig/network file: HOSTNAME=<hostname> where <hostname> is the same as in Step 1. 3. Specify the IP address to associate with the hostname in the /etc/hosts file. This should be static and not served by DHCP. The proxy uses this IP address in features such as transparent authentication and hierarchical caching. This must be the first line in the file. Do not delete the second and third lines (the ones that begin with “127.0.0.1” and “::1”, respectively). xxx.xxx.xxx.xxx <FQDN> <hostname> 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 <FQDN> is the fully-qualified domain name of this machine (i.e., <hostname>.<subdomain(s)>.<top-level domain>). For example: myhost.example.com <hostname> is the same name specified in Step 1. Do not reverse the order of the FQDN and hostname. 4. Configure DNS in the /etc/resolv.conf file. search <subdomain1>.<top-level domain> <subdomain2>.<toplevel domain> <subdomain3>.<top-level domain> nameserver xxx.xxx.xxx.xxx nameserver xxx.xxx.xxx.xxx This example demonstrates that more than one domain can be listed on the search line. Listing several domains may have an impact on performance, because each domain is searched until a match is found. Also, this example shows a primary and secondary nameserver being specified. 5. Gather this information: Default gateway (or other routing information) List of your company’s DNS servers and their IP addresses DNS domains to search, such as internal domain names. Include any legacy domain names that your company might have acquired. List of additional firewall ports to open beyond SSH (22) and the proxy ports (8080-8090). See Ports. Deployment and Installation Center 229 Installing Websense Content Gateway Preparing a cache disk for use by Websense Content Gateway For Websense Content Gateway to operate as a caching proxy, it must have access to at least one raw disk. Otherwise, Content Gateway can function as a proxy only. To create a raw disk for the proxy cache when all disks have a mounted file system: Note This procedure is necessary only if you want to use a disk already mounted to a file system as a cache disk for Content Gateway. Perform this procedure before installing Content Gateway. Warning Do not use an LVM (Logical Volume Manager) volume as a cache disk. Warning The Content Gateway installer will irretrievably clear the contents of cache disks. 1. Enter the following command at the prompt to examine which file systems are mounted on the disk you want to use for the proxy cache: df -k 2. Open the file /etc/fstab and comment out or delete the file system entries for the disk. 3. Save and close the file. 4. Enter the following command for each file system you want to unmount: umount <file_system> where <file_system> is the file system you want to unmount. When the Content Gateway installer prompts you for a cache disk, select the raw disk you created. Note It is possible to add cache disks after Content Gateway is installed. For instructions, see the Content Gateway Manager Help. 230 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway Preparing for a clustered deployment of Websense Content Gateway If you plan to deploy multiple, clustered instances of Websense Content Gateway (Content Gateway): Find the name of the network interface you want to use for cluster communication. This must be a dedicated interface. Find or define a multicast group IP address. Note If a multicast group IP address has not already been defined, enter the following at a command line to define the multicast route: route add <multicast.group address>/32 dev <interface_name> where <interface_name> is the name of the interface used for cluster communication. For example: route add 224.0.1.37/32 dev eth1 Installing Websense Content Gateway Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Security Gateway and Web Security Gateway Anywhere, v7.7.x Installing Websense Content Gateway Complete these steps to install Websense Content Gateway (Content Gateway) on a server in a software-base deployment of Websense software. In a Websenseappliance-based deployment, Content Gateway is already installed on the appliance. Before you begin, be sure to read Preparing to install Websense Content Gateway. 1. Disable any currently running firewall on this machine for the duration of Content Gateway installation.

To install the missing packages, the operating system must have a repository of available libraries. The Media repository on the Red Hat Enterprise Linux install DVD is an acceptable source of packages. After the repository is setup, all of the required dependencies can be automatically resolved by running: yum install wcg_deps-1-0.noarch.rpm 240 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway The above RPM is included in the Content Gateway install tree, at the same level as wcg_install.sh. Installing on Red Hat Enterprise Linux 6, update 1 and higher biosdevname Red Hat Enterprise Linux 6, update 1 introduces biosdevname. biosdevname is not supported by Content Gateway version 7.7.x and lower. What is biosdevname? The Red Hat Enterprise Linux update 6.1 release notes state: ... biosdevname [is an] optional convention for naming network interfaces. biosdevname assigns names to network interfaces based on their physical location. ... biosdevname is disabled by default, except for a limited set of Dell systems. biosdevname is designed to replace the older, inconsistent “eth#” naming scheme. The new standard will be very helpful when it is fully adopted, however it is not yet fully adopted. The presence of a single Ethernet device absent the SMIBIOS Slot # and biosdevname field causes the Red Hat Enterprise Linux 6.1 installer and 'udev' to fall back to the preferred eth# device naming for all interfaces. Important To ensure interface name consistency among hardware platforms and Red Hat Enterprise Linux 6.0, 6.1, and higher, Content Gateway version 7.7.x requires “eth#” names. If any non-“eth#” names exist, the Content Gateway installer exits and provides a link to instructions for modifying system startup files. Upgrading from Red Hat Enterprise Linux 6.0 to 6.1 and higher poses no risk. There was no biosdevname support in Update 6.0 and device names are not altered by the upgrade to 6.1 or higher. Disabling biosdevname If while installing Content Gateway the installer finds non-eth# interface names, the installer quits and provides a link to instructions for modifying system startup files. There are 2 ways to disable biosdevname: 1. During operating system installation. 2. Post-operating system installation through modification of several system files and other activities. The easiest way to disable biosdevname is to do it during operating system installation. This is the recommend method. Deployment and Installation Center 241 Installing Websense Content Gateway Disabling biosdevname during operating system installation: 242 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway When the installer starts, press [TAB] and alter the boot line to add “biosdevname=0” as follows: Proceed through the rest of the installer as usual. Disabling biosdevname after operating system installation: Log on to the operating system and verify that non-eth# names are present. ifconfig -a If only “eth#” and “lo” names are present, you are done. No other actions are required. Deployment and Installation Center 243 Installing Websense Content Gateway If there are names like “emb#” or “p#p#” perform the following steps. 1. Log in as root. 2. cd /etc/sysconfig/network-scripts 3. Rename all “ifcfg-<ifname>” files except “ifcfg-lo” so that they are named “ifcfg-eth#”. a. Start by renaming “ifcfg-em1” to “ifcfg-eth0” and continue with the rest of the “ifcfg-em#” files. b. When the above are done, rename the “ifcfg-p#p#” files. If there are multiple “ifcfg-p#p1” interfaces, rename all of them in the order of the lowest “ifcfg-p#” first. For example, if the initial set of interfaces presented by “`ifconfig -a” is: em1 em2 em3 em4 p1p1 p1p2 p2p1 p2p2 em1 -> eth0 em2 -> eth1 em3 -> eth2 em4 -> eth3 p1p1 -> eth4 p1p2 -> eth5 244 Websense Web Security Gateway and Gateway Anywhere Installing Websense Content Gateway p2p1 -> eth6 p2p2 -> eth7 c. Make the “ifcfg-eth#” files linear so that if you have 6 interfaces you have eth0 through eth5. 4. Edit all the ifcfg-eth# files. a. Update the DEVICE= sections to refer to the new name: “eth#” b. Update the NAME= sections to refer to the new name: “System eth#” 5. Remove the old udev device mapping file if it exists: rm -f /etc/udev/rules.d/70-persistent-net.rules 6. Modify the “grub.conf” file to disable biosdevname for the kernel you boot. a. Edit /boot/grub/grub.conf b. Add the following to the end of your “kernel /vmlinuz” line: biosdevname=0 7. Reboot. 8. Reconfigure the interfaces as required. Installer gives NetworkManager or avahi-daemon error Warning Content Gateway is supported on Red Hat Enterprise Linux 6, Basic Server (no GUI). It is not supported on Red Hat Enterprise Linux 6 with a GUI. When Red Hat Enterprise Linux 6 is installed with a GUI, the Content Gateway installer recognizes systems running NetworkManager or avahi-daemon processes and emits an error similar to: Error: The avahi-daemon service is enabled on this system and must be disabled before Websense Content Gateway v7.7 can be installed. Please disable the avahi-daemon service with the following commands and restart the Websense Content Gateway installation. chkconfig --levels 2345 avahi-daemon off service avahi-daemon stop To continue, the conflicting NetworkManager and avahi-daemon processes must be stopped. 1.

V-Series appliances Websense Web Security and Email Security solutions are supported on the following V-Series appliances: Websense V10000 Websense V10000 G2 Websense V5000 G2 Websense V10000 The Websense V10000 appliance provides the majority of Web Security Gateway functions. Web traffic is directed through the Websense appliance for filtering. Only the Web Security Gateway module is supported on the V10000 appliance. Web Security and Email Security Gateway modules are not supported. Note V10000 appliances must upgraded to version 7.7.x with the V-Series upgrade patch. There is not a v7.7 recovery (ISO) image for V10000. 260 Websense V-Series Appliances Installing appliance-based Websense solutions Websense V10000 G2 The Websense V10000 G2 appliance provides the majority of Web Security, Web Security Gateway, and Email Security Gateway functions. For Web Security deployments, Web traffic is directed through the Websense appliance for filtering. For Email Security deployments, incoming email flows from the email hybrid service (if enabled) to the Websense appliance and to your mail server. The Websense appliance also provides the Personal Email Manager facility for end users to manage quarantined email. Websense V5000 G2 The Websense V5000 G2 appliance provides the majority of Web Security, Web Security Gateway, and Email Security Gateway functions. The V5000 appliance can also be configured in dual mode with Web Security and Email Security Gateway. A Web Security Gateway and Email Security Gateway dual-mode deployment is supported only on a V10000 G2 appliance. For Web Security deployments, Web traffic is directed through the Websense appliance for filtering. For Email Security deployments, incoming email flows from the email hybrid service (if enabled) to the Websense appliance and to your mail server. The Websense appliance also provides the Personal Email Manager facility for end users to manage quarantined email. Content Gateway Websense Content Gateway (Content Gateway) is a Linux-based, high-performance Web proxy and cache that provides real-time content scanning and Web site classification to protect network computers from malicious Web content while controlling employee access to dynamic, user-generated Web 2.0 content. Web content has evolved from a static information source to a sophisticated platform for 2-way communications, which can be a valuable productivity tool when adequately secured. Personal Email Manager Personal Email Manager is a tool that allows an end user to manage email that has been blocked by Websense Email Security Gateway. Occasionally Email Security may block email that is safe and that should be delivered. Personal Email Manager notifies an end user of blocked email and provides the means to manage it, either by permitting mail delivery or blocking a message from reaching a user’s inbox. Deployment and Installation Center 261 Installing appliance-based Websense solutions Off-appliance components The following Websense software and third-party components do not run on V-Series appliances. Microsoft SQL Server Websense reporting databases are hosted by Microsoft SQL Server. The reporting databases store Websense logging, reporting, and (for some modules) configuration data. With Email Security Gateway, quarantined email messages are stored here as well. SQL Server is not included as part of a Websense subscription. In most cases, when you install Websense components, SQL Server must already be installed and running on a separate machine. In very small deployments, or for evaluation, the TRITON Unified Installer can be used to install SQL Server 2008 R2 Express, either on the TRITON management server or on a separate Windows machine. TRITON management server The TRITON management server is the machine that hosts the TRITON Unified Security Center (TRITON console), the management and reporting console for Websense Web Security, Email Security, and Data Security. This machine manages your entire Websense deployment. It includes TRITON Infrastructure and the TRITON console management modules that you select. The 3 TRITON management modules are: TRITON - Web Security TRITON - Data Security TRITON - Email Security In an Email Security Gateway deployment, the TRITON management server includes both TRITON - Email Security and TRITON - Data Security, as well as additional Data Security components. TRITON - Data Security is used to configure email DLP (data loss prevention) features. In a Web Security Gateway Anywhere deployment, the TRITON management server also includes TRITON - Data Security and other Data Security components in order to enable Web DLP functionality. Additional, optional components can also run on this machine. See TRITON management server, page 733, for more information. In Web Security deployments, Real-Time Monitor is automatically installed on the TRITON management server. In Web Security Gateway Anywhere deployments, Linking Service is also typically installed on this machine. 262 Websense V-Series Appliances Installing appliance-based Websense solutions Reporting components Both Web Security and Email Security solutions use a component called Log Server to pass information to the SQL Server reporting database (Log Database) for use in generating reports. Web Security Log Server and Email Security Log Server are Windows-only components. Other off-appliance Web Security components The following Web Security components, if used, must be installed off the appliance: Transparent identification agents (DC Agent, Logon Agent, eDirectory Agent, and RADIUS Agent).

Important Changing the C interface IP address significantly impacts the deployment and may require reinstallation of some components. If your appliance is in production and you need to change the C interface IP address, see the embedded Appliance Manager Help system for guidance. Guidelines for configuring network interface C IP address (C interface) Required. This interface typically requires continual access to the Internet, though some sites use P1 for all communication with the Internet. If you change the IP address of the C interface, the update process may take about 10 minutes. After the IP address is changed, you are redirected to a logon page. Enter your user name and password. The Status > General page will show that the services are starting up. Wait for all required services to start (optional services include: Directory Agent, State Server, Multiplexer, and TRITON - Web Security manager). Subnet mask (C) Required. Deployment and Installation Center 279 Setting Up Websense V-Series Appliances Default gateway (C) Optional. IP address of the router that allows traffic to be routed outside of the subnet.

Websense Content Gateway Interfaces (P1 and P2) Deployment and Installation Center | Web and Email Security Solutions | Version 7.7.x Applies to: Web Security Gateway and Web Security Gateway Anywhere v7.7.x V10000, V10000 G2, and V5000 G2 v7.7.x The Websense Content Gateway Interfaces (P1 and P2) handle traffic directed to and from the Websense Content Gateway proxy module. Both the P1 and P2 proxy interfaces can be used to accept users’ Internet requests (inbound traffic) and communicate with Web servers (outbound traffic). In other words, both interfaces can be configured to handle traffic into and out of the proxy module. A typical configuration is to use P1 for both inbound and outbound traffic; P2 is not used. Another option is to configure P1 to accept users’ Internet requests (inbound only). In this case, P2 is configured to communicate with Web servers (outbound). Important If you use the P2 interface, the P1 interface is bound to eth0, and the P2 interface is bound to eth1. Keep this in mind when you configure Websense Content Gateway. For example, suppose you are using a transparent proxy deployment, and the P1 interface is connected to a WCCP router. In this case, you must configure Websense Content Gateway to use eth0 for WCCP communications (in Content Gateway Manager, see the General tab of the Configure > Networking > WCCP page). 280 Websense V-Series Appliances Setting Up Websense V-Series Appliances Guidelines for configuring network interfaces P1 and P2 General guideline If you use both P1 and P2, and configure them in the same subnet, the default gateway is automatically bonded on P2. Ensure that outbound packets can reach the Internet. IP address (P1 or P2 interface) Required. Subnet mask Required. Default gateway Required. The gateway must be in the same subnet as the IP address of the interface (P1 or P2) used for communicating with the Internet (outbound traffic). If you use both P1 and P2, they must be located in the same subnet. The default gateway is automatically assigned to P2 (which is bound to eth1). Ensure that outbound packets can reach the Internet. Primary DNS Required. IP address of the domain name server. Secondary DNS Optional. Serves as a backup in case the primary DNS is unavailable. Tertiary DNS Optional. Serves as a backup in case the primary and secondary DNSes are unavailable. Network Agent Interface (N) Deployment and Installation Center | Web and Email Security Solutions | Version 7.7.x Applies to: Web Security v7.7.x Web Security Gateway and Web Security Gateway Anywhere v7.7.x V10000, V10000 G2, and V5000 G2 v7.7.x Network Agent is a software component used to filter protocols other than HTTP and HTTPS. It provides bandwidth optimization data and enhanced logging detail. Network Agent continually monitors overall network usage, including bytes transferred over the network. The agent sends usage summaries to other Websense software at predefined intervals. Network Agent is typically configured to see both inbound and outbound traffic in your network. The agent distinguishes between: Requests sent from internal machines to internal machines (hits to an intranet server, for example) Deployment and Installation Center 281 Setting Up Websense V-Series Appliances Requests sent from internal machines to external machines such as Web servers (user Internet requests, for example) You choose whether blocking information for non-HTTP protocols is routed through interface C or interface N. Guidelines for configuring network interface N Select an interface to use to send blocking information for non-HTTP and HTTPS traffic Select Interface C only if you want to use interface C to send blocking information. Select Interface N if network interface N is connected to a bidirectional span port, and you want to use N to transport blocking information. Blocking NIC settings configured in TRITON - Web Security do not override the settings you enter in this pane. The settings in Appliance Manager take precedence. IP address of interface N Optional, unless interface N is selected to transport blocking information (above), in which case it’s required. Network Agent should be able to see the outbound and inbound traffic in your network. Network Agent ignores ports 80, 443, 8070, and 8080. Subnet mask Required if interface N is selected. Otherwise the subnet mask has a fixed value of 255.255.255.255. Default gateway Required if Interface N is checked. Otherwise, the field is disabled. Primary DNS Required. IP address of the domain name server. Secondary DNS Optional. Serves as a backup in case the primary DNS is unavailable. Tertiary DNS Optional. Serves as a backup in case the primary and secondary DNSes are unavailable. Network Agent can instead be installed on a different server in the network. Email Security Gateway Interfaces (E1 and E2, or P1 and P2) Deployment and Installation Center | Web and Email Security Solutions | Version 7.7.x Applies to: Email Security Gateway and Email Security Gateway Anywhere v7.7.x V10000 G2 and V5000 G2 v7.7.x Websense Email Security Gateway Interfaces handle traffic into and out of the Websense Email Security Gateway module. It is important that you set up interfaces 282 Websense V-Series Appliances Setting Up Websense V-Series Appliances E1, E2, and C correctly before deploying off-appliance components. TRITON Unified Security Center installation cannot complete unless these interfaces are correctly configured. Note The names of the interfaces vary depending on the model of V-Series appliance. On V10000 G2, E1 and E2 are used. On V5000 G2, P1 and P2 are used. Both the E1 and E2 interfaces can be used to accept inbound traffic and send outbound traffic. On V5000 G2, use P1 and P2. A typical configuration is to use E1 (P1) for both inbound and outbound traffic; E2 (P2) is not used. Another option is to configure E1 (P1) to accept inbound and E2 (P2) to send outbound traffic. When you need to support a large volume of outbound traffic, you can configure virtual interfaces on E1 or E2 (P1 or P2). Important On the V10000 G2, if you use the E2 interface, the E1 interface is bound to eth0, and the E2 interface is bound to eth1. Keep this in mind when you configure Websense Email Security Gateway. On the V5000 G2, if you use the P2 interface, the P1 interface is bound to eth0, and the P2 interface is bound to eth1. Keep this in mind when you configure Websense Email Security Gateway. Guidelines for configuring network interfaces E1 and E2 Please note the following important guidelines for configuring the E1 and E2 interfaces for Email Security: If you use both the E1 and E2 interfaces, it is recommended that you do not configure them in the same subnet. Using both E1 and E2 and locating them in the same subnet can disrupt (or even stop) mail flow, depending on your network topology. In this situation, you should examine your routing table and adjust it manually if necessary to allow network traffic to flow smoothly. Deployment and Installation Center 283 Setting Up Websense V-Series Appliances The gateway must be in the same subnet as the IP address of the interface (E1 or E2) used for communicating with the Internet (outbound traffic). Ensure that all outbound packets can reach the Internet. IP address (E1 or E2 interface) Required. E1 is used by default to connect to SQL Server for reporting. If E1 does not have a valid IP address or does not have DNS access, then Email Security Gateway cannot resolve the SQL Server hostname and cannot create a connection with SQL Server. Off-box installation of the management console is then blocked. On a V5000 G2, substitute P1 for E1. Subnet mask Required. Default gateway Required. The gateway must be in the same subnet as the IP address of the interface (E1 or E2) used for communicating with the Internet (outbound traffic). If you use both E1 and E2, and you locate them in the same subnet, then the default gateway is automatically assigned to E2 (which is bound to eth1). Ensure that outbound packets can reach the Internet. Primary DNS Required. IP address of the domain name server. Secondary DNS Optional. Serves as a backup in case the primary DNS is unavailable. Tertiary DNS Optional. Serves as a backup in case the primary and secondary DNSes are unavailable. Email Security virtual interfaces Multiple virtual IP addresses can be configured on E1 or E2. Virtual IP addresses are used for outbound traffic only. Virtual IP addresses are bound to the specified physical interface. Virtual IP addresses must be in the same subnet as the specified physical interface. A maximum of 10 virtual IP addresses can be specified for each physical interface (E1 and E2). Multiple virtual interfaces can be helpful to support multiple domains or a large volume of outbound traffic. To add virtual IP addresses to E1 or E2: 1. Go to Configuration > Network Interfaces > Virtual Interfaces and click Add. 2. Select E1 or E2. If E2 has not been configured, it is not offered. 3.

Configuration details are provided below. Interface bonding is not supported on V5000 G2 appliances. Important Do not bond interfaces that have different speeds or duplex modes. Doing so can result in performance problems. V10000/V10000 G2 with Websense Web Security only Interfaces E1 and E2 can be cabled to your network and then bonded through software settings to a Websense Content Gateway interface, with E1 optionally bonded to P1, and E2 optionally bonded to P2. No other pairing is possible. Interface bonding provides these alternatives: Active/Standby mode: P1 (or P2) is active, and E1 (or E2) is in standby mode. Only if the primary interface fails would its bonded interface (E1 or E2) become active. Load balancing: If the switch or router that is directly connected to the V10000/ V10000 G2 supports load balancing (etherchannel, trunk group, or similar), then traffic to and from the primary interface can be balanced between the primary interface and its bonded interface (E1 or E2). You can choose to bond or not bond each Websense Content Gateway interface (P1 and P2) independently. You do not have to bond at all. Deployment and Installation Center 285 Setting Up Websense V-Series Appliances If you do bond an interface (P1 or P2), choose one mode for that bonding (either active/standby or load balancing). You do not have to choose the same bonding mode for both. Ensure that all interfaces are cabled properly before bonding. Do not bond interfaces that have different speeds or duplex modes. Doing so can result in performance problems. V10000 G2 with Websense Email Security Gateway only Interfaces P1 and P2 can be cabled to your network and then bonded through software settings to a Websense Email Security Gateway interface, with P1 optionally bonded to E1, and P2 optionally bonded to E2. No other pairing is possible. Interface bonding provides these alternatives: Active/Standby mode: E1 (or E2) is active, and P1 (or P2) is in standby mode. Only if the primary interface fails would its bonded interface (P1 or P2) become active. Load balancing: If the switch or router that is directly connected to the V10000 G2 supports load balancing (etherchannel, trunk group, or similar), then traffic to and from the primary interface can be balanced between the primary interface and its bonded interface (P1 or P2). You can choose to bond or not bond each Websense Email Security Gateway interface (E1 and E2) independently. You do not have to bond at all. If you do bond an interface (E1 or E2), choose one mode for that bonding (either active/standby or load balancing). You do not have to choose the same bonding mode for both.

If IPv6 is enabled, static IPv6 routes can also be added and imported. Module routes from appliance modules through appliance interface C to subnets. IPv6 module routes are not supported. Configuring static routes Static routes can be specified for any active interface on the appliance, except N, which is dedicated to Network Agent and cannot be routed. The same route cannot be added for 2 different interfaces on the same module. If attempted, the appliance displays an error. Static routes that are defined for an interface that is later made inactive remain in the routing table, and are displayed in gray to indicate that the routes are inactive. Static routes that become invalid because the IP address of the interface changes are disabled and displayed in red. Static routes can be added and deleted, but not modified. To modify a route, delete it and add a new route specifying the new values. When a static route is added, imported, or deleted, the services associated with the module that manage the specified interface must be restarted. For example, if static routes are added to interface P1, when the additions are complete, all Content Gateway services must be restarted. The static route table has a maximum limit of 5000 entries. Adding static routes Static routes can be added one at a time, or many at a time using an import file. Deployment and Installation Center 287 Setting Up Websense V-Series Appliances When a static route is added, data entered in each field is validated by the appliance, and an error message is displayed if there is an inconsistency in the route. To add static routes: 1. Go to the Configuration > Routing page, select the IPv4 or IPv6 tab, and click Add/Import under Static Routes. 2. To manually add a single route, select the Add individual route radio button, enter values for all fields, and then click Add Route. Destination Network Required. Specify the subnet IP address for whichtraffic will be routed. Subnet Mask (IPv4) or Subnet prefix length (IPv6) Required. The subnet mask or prefix for the network where the clients reside (such as 255.255.0.0, or 64) Gateway Required. IP address providing access from the proxy subnet to the client subnet. This address must be on the same subnet as the appliance. Interface Required. The appliance interface to be used for the static route. Only active interfaces are offered in the drop down list. 3. To add multiple routes using an import list file: a. Prepare the import file. See Import file specifications, below. b. Select the Import route file radio button. c. Specify the full path and file name, or Browse to locate the file. Click Import Route to import the routes specified in the file. The appliance reads the file, validates each route, and reports errors for lines that are invalid. Duplicate route entries are ignored; duplicate entries are not created. If the number of routes in the file, combined with the number of existing routes exceeds the 5000 route table limit, the import fails. No routes are added and an error message displays. Import file specifications: 1. The file must be a plain text file. (Most routers export route tables to a plain text file.) 2. The file can contain comment lines. Comment lines begin with “#”. 3. A line that defines a route must include the following 4 fields in the order shown. Each field must be separated by a space. For IPv4: destination netmask default-gateway interface Destination is a subnet address or host IP address. 288 Websense V-Series Appliances Setting Up Websense V-Series Appliances Netmask determines the proper value of destination. Default-gateway is the next hop. Interface is the appliance interface through which traffic is routed. The specified interface must be enabled. If it is disabled, the appliance reports an error and does not add the route. For IPv6: destination prefix-length default-gateway interface Destination is a subnet address or host IP address. Prefix-length determines the proper value of destination. Default-gateway is the next hop. Interface is the appliance interface through which traffic is routed. The specified interface must be enabled. If it is disabled, the appliance reports an error and does not add the route. Exporting the route table To export the route table to a text file, click Export Table. Use the Browse dialog to specify a location and name for the file. All routes in the table, whether enabled or disabled, are exported. The file is formatted as described above for import files. Configuring module routes In some deployments it is necessary or desirable to route some Web Security or Email Security traffic through the appliance C interface (typically Web and email traffic is routed through separate, dedicated interfaces (P1/P2, E1/E2) and C is reserved for management traffic). However, some sites might want to route authentication (or other) traffic through the C interface. This is accomplished by defining module routes on the Configuration > Routing page. The module route table has a maximum limit of 5000 entries. Adding a module route 1. In the Module Route section of the Configuration > Routing page, click Add. Deployment and Installation Center 289 Setting Up Websense V-Series Appliances 2. Specify a value for each field and click Add Route. Module Required. Select a module from the drop down list. The list displays only modules installed on the appliance. The Network Agent module may be installed, but will not appear in the list. Destination subnet Required. Specify the subnet IP address for which traffic will be routed. Subnet mask Required. The subnet mask for the destination subnet. Note It is the responsibility of the administrator to verify that the endpoint is available on the subnet. Alerting Deployment and Installation Center | Web and Email Security Solutions | Version 7.7.x Applies to: Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Email Security Gateway and Email Security Gateway Anywhere, v7.7.x In this topic Enable SNMP polling (monitoring), page 290 Enable SNMP traps, page 291 Enable specific alerts, page 292 V10000, V10000 G2, and V5000 G2, v7.7.x Use the Configuration > Alerting page to enable and configure SNMP alerting. There are 2 methods of SNMP alerting that you can enable on the Setup tab: Allow your SNMP manager to poll the appliance for standard SNMP counters (see Enable SNMP polling (monitoring)). Configure the appliance to send SNMP traps for selected events to your SNMP manager (see Enable SNMP traps). After enabling the SNMP trap server on the appliance, use the Alerts tab to configure which events cause a trap to be sent. See Enable specific alerts, page 292. Enable SNMP polling (monitoring) 1. Under Monitoring Server, click On. 290 Websense V-Series Appliances Setting Up Websense V-Series Appliances 2. Select the SNMP version (v1, v2c, or v3) used in your network. With SNMP v1 and v2c, a suffix (-wcg, -wws, -na, or -esg) is appended to the community name to indicate the originating module for the counter. With SNMP v3, you can specify the context name (WCG, WWS, NA, or ESG) to poll counters for each module. 3. If you selected v1 or v2c, provide the Community name for the appliance, and then click OK. You have completed your SNMP monitoring configuration. 4. If you selected v3, select the Security level (None, Authentication only, or Authentication and Encryption) used in your network, and the User name to associate with SNMP communication. 5. If you selected a security level that includes authentication, also enter the Password for the selected user name, then select the Authentication protocol (MD5 or SHA). 6. If you selected authentication and encryption, select the Encryption protocol (DES or AES), and then enter and confirm the Encryption key used for encryption. 7. Click OK to implement your changes. Enable SNMP traps Before enabling the appliance to send SNMP traps, download the appliance MIB file using the link in the Trap Server section of the Configuration > Alerting page. The MIB file must be installed in your SNMP manager before it can interpret traps sent by the appliance. When you are ready for the appliance to start sending SNMP traps: 1. Under Trap Server, click On, and then select the SNMP version (v1, v2c, or v3) used in your network. 2. For SNMP v1 or v2c, provide the following information: 3. The Community name to associate with traps sent by the appliance The IP address and port used by your SNMP manager. To verify your configuration, click Send Test Trap. If the test trap succeeds, click OK to apply and save your changes. See Enable specific alerts, page 292, to configure which events cause a trap to be sent. If there is a problem sending the test trap, verify the community name, IP address, and port, and make sure that the network allows communication between the appliance C interface and the SNMP manager. 4. For SNMP v3, enter the Engine ID and IP address of your SNMP manager, as well as the Port used for SNMP communication. 5. Select the Security level (None, Authentication only, or Authentication and Encryption) used in your network, and the User name to associate with SNMP communication. Deployment and Installation Center 291 Setting Up Websense V-Series Appliances 6. If you selected a security level that includes authentication, also enter and confirm the Password for the selected user name, then select the Authentication protocol (MD5 or SHA). 7. If you selected authentication and encryption, select the Encryption protocol (DES or AES), and then enter the Privacy password used for encryption. 8. To verify your configuration, click Send Test Trap. If the test trap succeeds, click OK to implement your changes. See Enable specific alerts, page 292, to configure which events cause a trap to be sent. If there is a problem sending the test trap, verify the community name, IP address, and port, and make sure that the network allows communication between the appliance and the SNMP manager. Enable specific alerts The appliance can send traps for each of its modules: Appliance Controller, Websense Content Gateway, Websense Web Security, Network Agent, and Email Security Gateway. The Alerts tab of the Configuration > Alerting page lists the alerts associated with only the modules that you have enabled. A table for each module lists: The hardware or software Event that triggers the alert (for example, a network interface link going down or coming up, or a Websense service stopping). The Threshold, if applicable, that defines the alert condition (for example, CPU usage exceeding 90%, or free disk space reaching less than 10% of the total disk size). The Type of alert (system resource or operational event). Whether or not an SNMP trap is sent when the event occurs or the threshold is reached. To enable all alerts for a module, select the check box next to SNMP in the table header. All check boxes in the column are selected. Otherwise, mark the check box next to an event name to enable SNMP alerts for that event. To disable alerts for an event, clear the associated check box. Time-based thresholds: Most of the events that have a configurable threshold also have a configurable time-based threshold, specified in minutes. When the time-based threshold is set and both thresholds are exceeded, an alert is sent. To enable time-based thresholds, select the Enable time-based thresholds check box at the top of the page. The time-based threshold is enabled on every event for which it is configurable. Event-cleared alerts: In addition to generating event condition alerts, you can configure alerts to be sent when conditions return below the threshold. These are called event-cleared alerts. To enable event-cleared alerts, select the Generate event-cleared alerts check box at the top of the page. The following events do not generate event-cleared alerts: 292 Websense V-Series Appliances Setting Up Websense V-Series Appliances Hostname change IP address change Scheduled backup failure SNMP authentication failure When you have finished configuring alerts, click OK to implement the changes.

Also define the TRITON - Web Security location. Under Policy Source, select which Web Security configuration is used on this appliance: Full policy source (default; see What is a policy source?), User directory and filtering, or Filtering only (see What if an appliance is not the policy source?). If this is a Full policy source appliance, it acts as both the Policy Broker and a Policy Server. There can be only 1 Full policy source appliance in your network. If this is a User directory and filtering appliance, it also acts as a Policy Server. Enter the IP address of the Policy Broker appliance or server. If this is a Filtering only appliance, enter the IP address of a Policy Server. It does not have to be the IP address of the Policy Broker machine. 1. Click OK to save and apply your changes. Deployment and Installation Center 293 Setting Up Websense V-Series Appliances 2. If this is a Web Security only (or Web Security Gateway only) appliance running as a Full policy source, under Web Security Components > TRITON - Web Security, specify whether to use the TRITON instance installed On the appliance, or whether to use an Off-appliance instance. Note When you upgrade from an earlier version of the appliance, your previous settings are preserved. If you do not have an off-appliance management console location already established, the system uses TRITON - Web Security on the policy source appliance by default. If you are using Websense Data Security or Email Security Gateway in conjunction with Websense Web Security Gateway, the TRITON Unified Security Center must be installed on a Windows Server 2008 R2 64-bit machine. Generally, the on-appliance installation of TRITON - Web Security is intended for evaluations and small deployments. Most production sites are advised to download the TRITON installer from mywebsense.com and install the TRITON console on a separate Windows server. 3. If you are moving from using an off-appliance TRITON - Web Security instance to using the on-appliance instance, make sure you have backed up your original TRITON console. Then expand Import Configuration and browse to the location of your backup file. This allows you to move much of your existing configuration and policy information to the appliance, rather than having to recreate your settings. As always, be sure to verify the configuration in the new TRITON console, as some settings may not be preserved during migration. 4. Click OK to save and apply your changes. What is a policy source? Every Websense Web Security deployment must include a single policy source. This is an appliance or other server that hosts 2 components: Websense Policy Broker and Websense Policy Database. All other Websense appliances or other servers point to this machine and receive regular updates from it. This appliance (or other server) is called the policy source. When a Web Security only appliance (or Web Security Gateway only appliance) is configured as a policy source, all available Web Security components run on that appliance, including. Filtering Service Policy Database Policy Broker Policy Server 294 Websense V-Series Appliances Setting Up Websense V-Series Appliances User Service Directory Agent (required only for hybrid service) State Server (optional) Multiplexer (optional) Usage Monitor Control Service TRITON - Web Security (optional) • • • • • • • Reports Information Service Investigative Reports Scheduler Manager Web Server Reporting Web Server Central Access Unified Security Center Settings Database Websense Content Gateway module (only with Web Security Gateway) Network Agent module (required for Web Security; optional for Web Security Gateway) Windows-only services, like Log Server, and optional services, like transparent identification agents, still run on other machines. When a policy source appliance runs in Web and Email Security mode (hosting Websense Web Security Gateway and Email Security Gateway), the TRITON services are disabled by default. A non-appliance policy source is a server hosting Policy Broker. The Policy Database is automatically created and run on the Policy Broker machine. This machine typically also includes a Policy Server instance, and may include additional Websense software components. The Policy Database holds all filtering policies (including client definitions, filters, and filter components) for all appliances and all domains in the network. It also holds global configuration information that applies to the entire deployment. What if an appliance is not the policy source? A Websense V-Series appliance that is not serving as the policy source can be designated to run either User directory and filtering or Filtering only. A User directory and filtering appliance is a lightweight version of the policy source machine. It runs: Policy Server User Service Usage Monitor Filtering Service Control Service Deployment and Installation Center 295 Setting Up Websense V-Series Appliances Directory Agent Websense Content Gateway module (if Web Security Gateway is used) Network Agent module (required for Web Security; optional for Web Security Gateway) Having User Service and Policy Server on remote appliances means that you are able to obtain local network user names. Latency between User Service and Policy Server is eliminated, because both run on the same appliance. Whenever you make a policy change, that change is immediately updated on the policy source appliance. The change is pushed out to user directory and filtering appliances within 30 seconds. These appliances can continue filtering for as long as 14 days if their connection with the policy source machine is interrupted. So even if a network connection is poor or is lost, filtering continues as expected. A User directory and filtering appliance is configured to point to the full policy source for updates. A Filtering only appliance does not run Policy Server. It runs only: Filtering Service Control Service Websense Content Gateway module (if Web Security Gateway is used) Network Agent module (required for Web Security; optional for Web Security Gateway) A Filtering only appliance is configured to point to a Policy Server. This works best when the appliance is close to the Policy server and on the same network. These appliances require a continual connection to the centralized Policy Server, not only to stay current, but also to continue filtering. If the connection to the Policy Server becomes unavailable for any reason, filtering on a Filtering only appliance can continue for up to 3 hours. If the Policy Server machine is on a remote network, with a WAN connection, it can be difficult to obtain user name/IP address maps for the local users. User directory with V-Series appliances If your organization relies on user identification or authentication, each appliance that is running Websense User Service must be configured to talk to a user directory. Multiple appliances can talk to the same user directory, or to different user directories. Preparing for a hybrid configuration In Web Security Gateway Anywhere environments, some users may be filtered by the hybrid (SaaS) service. In this situation, an interoperability component on the appliance called Directory Agent is required to enable user-, group-, and domain(OU) based filtering. Directory Agent must be able to communicate with: A supported LDAP-based directory service: 296 Websense V-Series Appliances Setting Up Websense V-Series Appliances Windows Active Directory® (Mixed Mode) Windows Active Directory (Native Mode®) Oracle (Sun Java™) System Directory Novell eDirectory Websense Sync Service After deployment, use TRITON - Web Security to configure User Service and Directory Agent. User Service configuration is performed on the Settings > General > Directory Services page. Directory Agent configuration is performed on the Settings > Hybrid Configuration > Shared User Data page. You can have multiple Directory Agent instances. Each Directory Agent must use a unique, non-overlapping root context. Each Directory Agent instance must be associated with a different Policy Server. All Directory Agent instances must connect to a single Sync Service. (A deployment can have only one Sync Service instance.) You must configure the Sync Service connection manually for all supplemental Directory Agent instances (these are the Directory Agents running on User Directory and filtering, and Filtering only appliances). Communication is configured automatically for the Directory Agent instance that connects to the same Policy Server as Sync Service. See the TRITON Web Security Help for details. You can configure Directory Agent to use a different root context than User Service, and to process its directory data differently than User Service. Also, with Windows Active Directory, if User Service is configured to communicate with multiple global catalog servers, Directory Agent can communicate with all of them. Redundancy Internet usage filtering requires interaction between several Websense software components: User requests for Internet access are proxied by Content Gateway. User requests for Internet access may also be monitored by Network Agent. The requests are sent to Websense Filtering Service for processing. Filtering Service communicates with Policy Server and Policy Broker to apply the appropriate policy in response to the request. In some networks, additional machines may be used to deploy additional instances of Content Gateway, Filtering Service, Network Agent, or other components. For example, in a large, segmented network, you may need a separate Network Agent for each segment. Or, you might deploy the Remote Filtering Server on a separate Deployment and Installation Center 297 Setting Up Websense V-Series Appliances computer, to enable filtering of laptops and other computers that are outside the organization’s network. Check the Websense Deployment and Installation Center for component distribution options. Contact your Websense Sales Engineer, or your authorized Websense reseller, for assistance in planning a more complex deployment.

Follow the links for your deployment in Installation steps for appliance-based solutions, page 263 Note Before deploying off-appliance components, be sure to use Appliance Manager to configure the appliance interfaces that you plan to use [C, P1, P2 (optional), E1, and E2 (optional)]. At sites using Email Security Gateway, E1 is used by default to connect to SQL Server for reporting. If E1 does not have a valid IP address or does not have DNS access, then Email Security Gateway cannot resolve the SQL Server hostname and cannot create a connection with SQL Server. In that situation, off-box installation of the management console is blocked. [On a V5000 G2, substitute P1 for E1.] Note If Policy Broker runs on an appliance, only on-appliance instances of Policy Server can communicate with Policy Broker. In this case, Policy Server cannot be installed offappliance. If Policy Broker is installed off-appliance, however, both on-appliance and off-appliance instances of Policy Server can communicate with it. Note Additional instances of Web security filtering components may be installed on machines in your network to provide additional functions or distribute processing load. For example, you can install additional Websense Network Agent instances on machines in your network. Deployment and Installation Center 299 Setting Up Websense V-Series Appliances Creating a TRITON management server Important The appliance must be set up and configured before you create a TRITON management server.

Data Security protects against data loss by quickly analyzing data and enforcing customized policies automatically, whether users are on the network or offline. Administrators manage who can send what information, where, and how. Data Security can also work as a part of Websense TRITON Enterprise to protect the whole of your enterprise. The basic components of Websense Data Security are: The Data Security Management Server Optional Data Security servers The protector Agents Endpoints The Data Security Management Server, which resides on the TRITON management server, is the core of the system, providing complete data loss prevention analysis to the network. In addition, the Data Security Management Server gathers and stores all management statistics. For load balancing purposes, analysis can be shared among a number of Data Security servers. The protector can provide added blocking capabilities to the loss-prevention system. Optionally, the protector works in tandem with the Data Security Management Server. The Data Security Management Server performs discovery (performed by Crawler) and provides advanced analysis capabilities. The protector sits in the network, intercepts and analyzes traffic, and can either monitor or block traffic as needed. The protector supports analysis of SMTP, HTTP, FTP, Generic Text and IM traffic (chat and file transfer). The protector is also an integration point for third-party solutions that support ICAP. Deployment and Installation Center 303 Installing Data Security Solutions The protector fits into your existing network with minimum configuration and necessitates no network infrastructure changes. Websense Data Security agents are also an integral part of the system. These agents are installed on the relevant servers (the ISA agent on the Microsoft ISA server, printer agent on the print server, etc.) to enable Data Security to access the data necessary to analyze the traffic from these servers. Agents, such as the Data Endpoint, enable administrators to analyze content within a user’s working environment (PC, laptop, etc.) and block or monitor policy breaches. Deployment A basic deployment might have just one management server and one protector. The protector includes several agents, including SMTP, HTTP, FTP, IM, and ICAP. The servers are easily configurable to simply monitor or monitor and protect sensitive data. It is ideal for small to medium businesses with a single Internet egress point. The following illustration is a high-level diagram of a basic deployment of Data Security. Such a deployment is ideal for a smaller- to medium-sized organization with a single Internet egress point. Note that this illustration is intended to show the general distribution of components and does not include network details (such as segmenting, internal firewalls, routing, switching, and so forth). 304 Websense Data Security Solutions Installing Data Security Solutions The following illustration is a high-level diagram of a larger deployment of Data Security. This shows the extended capabilities of Data Security incorporated into a more complex network environment. It shows an extra Data Security server and several additional agents deployed for businesses with larger transaction volumes and numbers of users. Such a deployment is suited for large organizations with multiple Internet egress points distributed over multiple geographical locations. Very large deployments can have multiple Data Security servers and protectors. For diagrams of the most common customer deployments, see Most common deployments, page 112. Before you deploy your Data Security system, it is important to analyze your existing resources and define how security should be implemented to optimally benefit your specific organization. Plan your deployment by: 1. Deciding what data to protect, page 103 2. Determining where your confidential data resides, page 105 3. Determining your information flow, page 106 4. Defining the business owners for the data, page 106 5. Deciding who will manage incidents, page 107 6. Planning access control, page 107 7. Analyzing network structure, page 108 8. Planning network resources, page 109 9. Planning a phased approach, page 121 For additional deployment information, see: Deployment and Installation Center 305 Installing Data Security Solutions Integrating Data Security with Existing Infrastructure, page 125 Scaling Data Security, page 157 Installation For best practice, before installing Websense Data Security, you should obtain and install Microsoft SQL Server (Obtaining Microsoft SQL Server, page 21) and read the considerations described in Preparing for installation, page 14. Data Security installation involves 3 basic steps. 1. Installing TRITON Unified Security Center, page 181 This includes the TRITON infrastructure and TRITON Console. When you reach the Installation Type screen of the Websense installer, select Data Security (under TRITON Unified Security Center). Note that you can install the other modules if you want, but TRITON - Data Security is the only one necessary for a Data Security deployment. 2. Installing TRITON - Data Security, page 187. You are automatically prompted to do this when you install the TRITON Unified Security Center with Data Security selected. This includes the Data Security Management Server—a policy engine, crawler, fingerprint repository, and when applicable, an SMTP agent, and endpoint server. 3. Installing Data Security components, page 413. If desired, you can install one or more optional components for monitoring things like print servers, ISA/TMG servers, endpoint machines. You can also install extra Data Security servers and crawlers for system scaling. Websense Data Security supports installations over Virtual Machines (VM), but Microsoft SQL Server must be present to support the incident and policy database.

Deployment and Installation Center 313 Installing Data Security Solutions 314 Websense Data Security Solutions 16 Installing Data Security Components Deployment and Installation Center | Data Security Solutions | Version 7.7.x Once you’ve installed Data Security on the TRITON management server (as described in Creating a TRITON Management Server, page 180), you can install other Data Security components as needed. In larger deployments, you might install supplemental Data Security servers, crawlers, or policy engines. In some scenarios, you might install the Data Security protector and/or any number of Data Security agents such as the printer agent for monitoring printer output or ISA agent for monitoring data on Microsoft ISA servers. Data Security agents are installed on the relevant servers (ISA agent on the ISA server, printer agent on the print server, etc.) to enable Data Security to access the data necessary to analyze the traffic from these servers. The Data Endpoint agent enables administrators to analyze content within a user’s working environment (PC, laptop, etc.) and block or monitor policy breaches. Important If you plan to install a Data Security component—for example, a supplemental server or agent—TRITON Unified Security Center must already be installed in your network along with the Data Security Management Server software. Do not install any Data Security component on a domain controller. Installing supplemental Data Security servers, page 316 Installing Data Security agents, page 321 Deployment and Installation Center 315 Installing Data Security Components Installing supplemental Data Security servers Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: In this topic: Data Security, v7.7.x Operating system support, page 316 Hardware requirements, page 317 Software requirements, page 317 Required ports, page 318 Installation steps, page 318 Medium to large enterprises may require more than one Data Security server to perform content analysis efficiently.

With the exception of the protector, mobile agent, and Data Endpoint, Data Security agents are installed using the Custom option of the standard Websense installer. Note that the various agents become available only when you are performing the installation on a required server. For example, if you are running the installation wizard on an ISA server, the wizard knows this and lists the ISA agent as an option that you can install. Deployment and Installation Center 321 Installing Data Security Components Click the links to learn more about each agent, including where to deploy it, installation prerequisites, installation steps, special considerations, and best practices. Agent Description Protector The protector is a standard part of Websense Data Security deployments. It is a soft appliance with a policy engine and a fingerprint repository, and it supports analysis of SMTP, HTTP, HTTPS, FTP, plain text, and IM traffic (chat and file transfer). The protector is also an integration point for third-party solutions that support ICAP (when Websense Content Gateway is not used for this purpose). Note: For HTTPS traffic, the protector works with a Web proxy such as Websense Content Gateway. See Protector, page 324 for more information. SMTP agent SMTP is the protocol used for sending email to recipients outside the organization. The SMTP agent monitors SMTP traffic. It receives all outbound email from the mail server and forwards it to the Data Security policy engine. It then receives the analyzed email back from the policy engine, and blocks or forwards it to the mail gateway as directed See SMTP agent, page 355 for more information. ISA/TMG agent The ISA agent receives all Web (HTTP or HTTPS) connections from a Microsoft ISA or Forefront TMG Server network and forwards them to the Data Security policy engine. It then receives the analyzed information back from the policy engine and forwards it to the recipients on the Web. See Microsoft ISA/TMG agent, page 362 for more information. Endpoint agent Data Endpoint monitors all data activity on endpoint machines and reports on data at rest on those machines. With the endpoint agent, you can monitor application operations such as cut, copy, paste, and print screen and block users for copying files, or even parts of files, to endpoint devices such as thumb drives. The endpoint agent can also monitor or block print operations. See Installing and Deploying Websense Endpoint Clients, page 421 for more information. Printer agent The printer agent is installed on a Microsoft print server. It monitors data that is sent to network printers through optical character recognition (OCR) technology. See Printer agent, page 365 for more information. Web Content Gateway A Data Security policy engine is embedded in Websense Content Gateway. No agent installation is required; however, the policy engine is not active until registered with a TRITON management server. See Content Gateway Help for registration instructions. Email Security Gateway A Data Security policy engine is embedded in Email SecurityGateway. No agent installation is required; however, the policy engine is not active until registered with a TRITON management server. See the TRITON - Email Security Help for registration instructions. 322 Websense Data Security Installing Data Security Components Agent Description Mobile agent The mobile agent monitors and blocks activities on mobile devices that perform synchronization operations with the Exchange server. With the mobile agent, you can monitor and block data transmitted in email messages, calendar events, and tasks. It is on a Websense appliance, or you can install it on your own hardware. The mobile agent supports ActiveSync, which is a wireless communication protocol used to push resources, such as email, from applications to mobile devices. See Mobile agent, page 339 for more information. Integration agent The Integration agent allows third-party products to send data to Websense Data Security for analysis. It is embedded in third-party installers and communicates with Data Security via a C-based API. See Integration agent, page 372 for more information. Crawler The crawler is the name of the agent that performs discovery and fingerprinting scans. The crawler is installed automatically on the TRITON Management Server and other Data Security servers. If you want to improve scanning performance in high transaction volume environments, you can install it stand-alone on another server as well. See The crawler, page 375 for more information. Important Data Security agents and machines with a policy engine (such as a Data Security Server or Websense Content Gateway machine) must have direct connection to the TRITON management server. When deployed in a DMZ or behind a firewall, the relevant ports must be allowed. Deployment and Installation Center 323 Installing Data Security Components Protector Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.7.x In this topic: When to use the protector, page 324 Deploying the protector, page 325 Hardware requirements, page 328 Recommended (optional) additional NICs for inline mode:, page 329 Required ports, page 329 Installing the protector software, page 330 Configuring the protector, page 337 The protector is an essential component of Websense Data Security, providing monitoring and blocking capabilities, preventing data loss and leaks of sensitive information. Using PreciseID technology, the protector can be configured to accurately monitor sensitive information-in-transit on any port. When to use the protector The protector works in tandem with the DataSecurity server. The Data Security server provides advanced analysis capabilities, while the protector sits on the network, intercepts traffic and can either monitor or block the traffic, as needed. The protector supports analysis of SMTP, HTTP, FTP, plain text, IM traffic (e.g., Yahoo, MSN, chat, and file transfer). The protector is also an integration point for third-party solutions that support ICAP. The protector fits into your existing network with minimum configuration and necessitates no network infrastructure changes. If you want to monitor SMTP traffic, the protector is your best choice. You configure a span port to be connected to the protector. This span contains your SMTP traffic. If you want email blocking capabilities, you can use either the protector’s explicit MTA mode or the SMTP agent (see below). We do not recommend that you use both options for the same traffic, although some companies prefer monitoring one point and enforcing policies on another, due to differences in network traffic content and load. 324 Websense Data Security Installing Data Security Components If you want to monitor or transparently block HTTP traffic, you can use the protector to do so, or you can integrate Data Security with Websense Content Gateway or another Web proxy. If you want to monitor FTP, plain text, or IM traffic, you should use the protector. Note that the protector cannot block traffic on these channels. You can block FTP using Websense Content Gateway (as a DLP agent) or other Web proxy that buffers FTP and supports ICAP. The first decision that needs to be made when installing a protector is its location on the network. You can deploy the protector in SPAN/mirror port mode or in inline mode. Deploying the protector Most data-loss detection devices can be connected off the network, enabling them to sniff network traffic and monitor breaches. This monitoring method is useful because it does not interfere with traffic; however, it also does not enable the loss-prevention system to prevent (block) data losses—only to note and report them. In addition to monitoring mode, you can connect the Websense Protector to the network directly in the path of the traffic, enabling traffic to be blocked, quarantined and even terminated before it reaches its destination. The following table depicts the available modes according to the selected topology. Topology Service SPAN/Mirror Port Inline/Bridge HTTP Monitoring Monitoring bridge Active (blocking) bridge SMTP Monitoring passive Mail Transfer Agent (MTA) Monitoring bridge Mail Transfer Agent (MTA) All Others Monitoring Monitoring ICAP Monitoring Blocking Monitoring Blocking Note In both inline/bridge and SPAN/mirror port topology, Websense Data Security can be integrated with Web proxies. Blocking and monitoring modes are both available. Deploying in SPAN/mirror port configuration In SPAN/mirror port mode, the protector is connected off the network via the SPAN/ mirror port of a switch, which enables the protector to sniff traffic and receive a copy for monitoring purposes, or via a SPAN/mirror device. In SPAN/mirror port mode, Deployment and Installation Center 325 Installing Data Security Components traffic is monitored and analyzed, but cannot be blocked. Note that the protector can also be connected to a TAP device. The following diagram depicts the Websense device connected to the network via a mirror port on a switch, transparently monitoring network traffic. Connect the protector to the mirror port of a switch on your network’s path. Connect the protector to the Data Security server. Deploying in inline configuration In inline/bridge mode, configure the protector as a layer-2 switch directly in the path of your organization’s traffic. In this configuration, the data security device functions passively, monitoring the traffic (as in monitoring mode), or actively, blocking traffic as necessary. When using the Websense Protector in inline mode, the hardware and software failsafe mechanism is available only when using the certified bypass-server adapter NIC. 326 Websense Data Security Installing Data Security Components The following Silicom network cards (NIC SKUs) are supported by the Websense Protector: PEG4BPi - Intel-based Quad-Port Copper Gigabit Ethernet PCI Express Bypass Server Adapter PEG2BPi - Intel-based Dual-Port Copper Gigabit Ethernet PCI Express Bypass Server Adapter PXG4BPi - Intel-based Quad-Port Copper Gigabit Ethernet PCI-X Bypass Server Adapter PXG2BPi - Intel-based Dual-Port Copper Gigabit Ethernet PCI-X Bypass Server Adapter The inline/bridge network setup is the same, regardless of whether the protector is activated in blocking or monitoring mode. The following figure depicts a sample setup for the Websense device in inline/ bridge topology. Connect the eth0 interface of the protector and the Data Security server to the LAN for management purposes, or use the port set while running the installation wizard. Connect the protector to the outgoing connection and to your organization’s internal network. Deployment and Installation Center 327 Installing Data Security Components The 2 most common inline (bridge) topologies include: HTTP in active (blocking) mode HTTP and SMTP in monitoring mode If you are planning to use one of these modes, when executing the Data Security Protector wizard, make sure the time, date and time zone are precise, and map eth0 to verify it is located on the main board. Connect eth0 of the protector to the LAN. In inline network configuration, the protector can monitor or block traffic. Monitoring bridge mode monitors traffic. SMTP MTA and HTTP Active Bridge modes have both monitoring and blocking options. Inline monitoring In inline monitoring mode, the protector actually sits in the data path on the network— however, data is monitored and not blocked. This mode is particularly useful during the setup phase, when testing the protector to make sure configuration is accurate and network-appropriate, before enabling blocking capabilities on the network. Inline blocking In inline blocking mode (also known as active bridge mode), the protector sits in the data path on the network. All traffic that traverses the protector is analyzed either locally by the policy engine resident on the protector, or by a Data Security server if load balancing is set up. The policy engine applies all policies as necessary before determining whether traffic is forwarded to its original destination. If data is detected that is supposed to be blocked, it is quarantined by the protector and does not reach its destinations. All traffic that does not match a policy and is not considered suspicious by the policy engine is forwarded by the protector to its original destination. The protector communicates with the Data Security server for management purposes as well as for fingerprinting and deployment updates. Hardware requirements The protector is a soft appliance. If you are using your own hardware, it must meet the following hardware requirements: Protector Minimum requirements Recommended CPU 2 Dual-core Intel Xeon processors (2.0 GHz) or AMD equivalent 2 Quad-core Intel Xeon processors (2.0 GHz) or AMD equivalent Memory 2 GB 4 GB Hard drives 2 - 72 GB 4 - 146 GB Disk space 70 GB 292 GB 328 Websense Data Security Installing Data Security Components Protector Minimum requirements Recommended Hardware RAID 1 1+0 NICs 2 (monitoring), 3 (inline) 2 (monitoring), 3 (inline) Recommended (optional) additional NICs for inline mode: The following Silicom network cards are supported by the Data Security appliance.

Configuring the network, page 331 2. Installation steps, page 331 3. Configure the protector in the TRITON Unified Security Center. See Final step: Verification, page 336. Protector installations include: A policy engine 330 Websense Data Security Installing Data Security Components ICAP client - for integration with third-party solutions that support ICAP, such as some Web proxies. Secondary fingerprint repository (the primary is on the management server) Configuring the network The following preparatory steps must be taken for the protector to be integrated into your network. Make sure that firewalls or other access control devices on your network do not block ports used by the protector to communicate with the Data Security server (see Protector, page 721). When installing the protector device in the network, both incoming and outgoing traffic (in the monitored segment) must be visible. In some cases, incoming traffic from the Internet and outgoing traffic to the Internet are on separate links. In this case, the mirror port must be configured to send traffic from both links to the protector. The protector needs to have access to the Data Security Management Server and vice versa. Installation steps You access the installation wizard for your protector through a command line interpreter (CLI). (See Data Security Protector CLI, page 793 for a reference guide.) To install the protector, do the following: 1. If you have purchased the Websense V5000 G2 Data Security Appliance, follow the instructions on its quick start poster to rack, cable, and power on the appliance. If you are using your own hardware: a. Use either a direct terminal or connect via serial port to access the command line. For serial port connection, configure your terminal application, such as HyperTerminal or TeraTerm, as follows: • • • • • 19200 baud 8 data bits no parity 1 stop bit no flow control b. The protector software is provided on an ISO image. Download the image, WebsenseDataSecurityProtector77x.iso, from MyWebsense and burn it to a CD. c. Place the CD in the protector’s CD drive and restart the machine. d. An installer page appears. If you are using a regular keyboard and screen, type kvm and press Enter. If you are using a serial console, press Enter. The machine is automatically restarted. 2. You’re prompted to enter a user name and password. Enter admin for both. Deployment and Installation Center 331 Installing Data Security Components When the protector CLI opens for the first time, logging in as admin automatically opens the installation wizard. On subsequent attempts, type “wizard” at the command prompt to access the wizard. 3. You have the option to install the Websense protector software or mobile agent software. Type P for Protector. Choose this mode whether you are deploying the protector inline or in a SPAN/mirror port configuration. For more information on deploying the protector inline, see Deploying in inline configuration, page 326. For more information on deploying the protector in a SPAN/mirror port configuration, see Deploying in SPAN/mirror port configuration, page 325. 4. Follow the instructions given by the wizard to configure basic settings. When the wizard requires data entry, it prompts you. In some cases, a default setting is provided (shown within brackets [ ]). If the default setting is acceptable, press <Enter> to keep the default value. STEP 1: Accept license agreement Each time the installation wizard opens, the end-user license agreement appears. Use the page-down/ scroll /space keys to read/scroll to the end of the agreement. Carefully read the license agreement, and when prompted, type yes to accept the license agreement. STEP 2: Select the hardware to install and confirm hardware requirements Data Security checks to see if your hardware meets the following requirements: 2 GB RAM 4 CPU 332 Websense Data Security Installing Data Security Components CPU with more than 2MB of cache CPU speed of 8000 bogomips Partition "/opt/websense/data" should have at least 45 GB If your requirements are substandard, you’re asked if you want to continue. STEP 3: Set administrator password 1. Type in and confirm a new password for the “admin” account. For security reasons, it is best practice to change the default password. 2. Type in and confirm a new Root (“root”) Password (mandatory). The root account provides full access to the device and should be used carefully. STEP 4: Set the NIC for management server and SSH connections A list of available network interfaces (NICs) appears. In this step, choose the NIC for use by the Data Security Management Server, SSH connections, and logging onto the protector (eth0 by default). All other NICs will be used for intercepting traffic. To help you identify which NIC to use, the wizard can simulate traffic for 0-60 seconds and cause LEDs to blink on that port. This does not work for all hardware and drivers. 1. Enter a number 0-60 to indicate how long (in seconds) you’d like traffic simulated or press Enter to skip this step. Deployment and Installation Center 333 Installing Data Security Components 2. When prompted, choose the NIC index number of the management NIC or accept the default interface. 3. Type the IP address of the NIC you’ve chosen. The default is 192.168.1.1. 4. Type the IP prefix of this NIC. This is the subnet mask in abbreviated format (number of bits in the subnet mask). The default is 24 (255.255.255.0). 5. Type a broadcast address for the NIC. The installation wizard will provide a calculated value, which is normally the desired one. 6. Type the IP address of the default gateway to be used to access the network. If the IP address of the Data Security server is not on the same subnet as the protector, a default gateway is required to tell the protector how to communicate with the Data Security server. 334 Websense Data Security Installing Data Security Components STEP 5: Define the host name and domain name 1. Type the host name to be used to identify this protector. The host name should be unique. 2. Optionally, type the domain name of the network into which the protector was added. The domain name set here will be used by the Data Security server when defining the protector’s parameters. STEP 6: Define the domain name server Optionally, type the IP address of the domain name server (DNS) that will service this protector. A DNS will allow access to other network resources using their names instead of their IP addresses. STEP 7: Set the date, time and time zone 1. Type the current time zone (to view a list of all timezones, type list). 2. Type the current date in the following format: dd-mmm-yyyy. 3. Type the current time in the following format: HH:MM:SS. Note that this is a 24hour clock. STEP 8: Register with a Data Security Server In this step, a secure channel will be created connecting the protector to a Data Security Server. This can be the Data Security Management Server or a supplemental server, depending on your set up. Deployment and Installation Center 335 Installing Data Security Components 1. Type the IP address or FQDN of the Data Security Server. Note that this must be the IP address identified when you installed the server machine. It cannot be a secondary IP address. 2. Type the user name and password for a TRITON - Data Security administrator that has privileges to manage system modules. Final step: Verification In the Data Security module of TRITON Unified Security Center, verify that the Websense Protector is no longer pending and that the icon displays its active status. Refresh the browser. Click Deploy. In the protector command-line interface, the following appears: The protector is now ready to be configured. See Initial Configuration for All Websense Modules, page 675 for instructions. 336 Websense Data Security Installing Data Security Components Configuring the protector To begin monitoring the network for sensitive information loss, you must perform some configuration in the TRITON - Data Security user interface. See the TRITON Unified Security Center Help system for instructions on logging on. Once logged on, navigate to Settings > Deployment > System Modules and doubleclick the installed protector. Define the channels that the Websense Protector will monitor. Supply additional configuration parameters needed by the Websense Data Security Server to define policies for unauthorized traffic. When you are done, make sure the protector does not have the status Disabled or Pending. You can view its status by looking at the System Modules page. For more configuration information, see “Configuring the protector” in the TRITON Data Security Help system. For instructions on configuring the protector for SMTP in monitoring bridge mode or MTA mode, see Using the protector, page 126. Setting up Bypass mode Bypass can be used in the event that the Bypass Server Adapter NIC was ordered with the protector; it enables transparent failover in the event of protector failure. When Bypass is enabled, if the protector malfunctions or is powered off, traffic will transparently pass through the protector to the external network. (Bypass mode is relevant only to the inline/bridge network topology.) Important Only certified Bypass Server Adapter NIC cards are tested and guaranteed to properly bypass the protector in the unlikely event of product failure. When a certified Bypass Server Adapter NIC dual or quad network card is available on the protector, it’s possible to enable the protector’s bypass mode. Bypass is a failsafe mechanism that shorts the protector in the unlikely event of device failure, enabling all network traffic to pass transparently through the protector to the network. You configure bypass mode in the TRITON - Data Security user interface. Select Settings > Configuration > System Modules. Select the protector, then navigate to the Networking tab and select Enable bypass mode. Refer to the TRITON - Data Security Help system for more details. Deployment and Installation Center 337 Installing Data Security Components By default, Bypass Mode is enabled. This means that when either a software or hardware problem occurs that causes the protector to malfunction, the protector will automatically be bypassed and the (unanalyzed) traffic will continue to pass to the outside network. If Bypass is disabled, when a malfunction occurs all traffic will be blocked and won’t reach its intended destination. Manual bypass To force the protector into bypass mode, causing all traffic to pass transparently through the protector, do the following: 1. Log onto TRITON - Data Security. 2. Select Settings > Deployment > System Modules. 3. Select the protector to bypass. 4. In the Edit Protector dialog, select the Networking tab. 5. Under Network Interfaces, click Edit. 6. Select the check box labeled, Enable bypass mode. 7. Select Force bypass. 8. Click OK twice. 9. Click Deploy. If you are experiencing network problems, you can verify that problems are not within the Data Security software, by setting Manual Bypass to On and noting if problems persist. 338 Websense Data Security Installing Data Security Components Mobile agent Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.7.x In this topic: Deploying the mobile agent, page 339 Hardware requirements, page 341 Required ports, page 341 Installing the mobile agent software, page 342 Configuring the mobile agent, page 352 Configuring a mobile DLP policy, page 354 The mobile agent is a Linux-based appliance that lets you secure the type of email content that is synchronized to users’ mobile devices when they connect to the network. This includes content in email messages, calendar events, and tasks. The mobile agent analyzes content when users synchronize their mobile devices to your organization’s Exchange server. If content or data being pushed to their device breaches the organization’s mobile DLP policy, it is quarantined or permitted accordingly. Deploying the mobile agent In your network, the appliance connects to the Data Security Management Server and to your Microsoft Exchange agent to provide this function. DLP analysis is done on the appliance or on other Data Security servers (rather than on the management server) to optimize performance and balance the load. Outside your DMZ, the mobile agent connects to any Microsoft ActiveSynccompatible mobile device over 3G and wireless networks, such as i-pads, Android mobile phones, and i-phones. (ActiveSync is a wireless communication protocol used to push resources, such as email, from applications to mobile devices.) Unlike the protector, the mobile agent appliance acts as a reverse proxy, because it retrieves resources, such as email, from the Exchange server on behalf of the mobile device. The following diagram illustrates the system architecture of a typical mobile agent deployment. Depending on your network and security requirements, you can also go Deployment and Installation Center 339 Installing Data Security Components through an edge device, such as a Microsoft ISA Server, that acts as a reverse proxy to the mobile agent. For system requirements, see Mobile Agent hardware requirements, page 13. For the default port numbers used by the mobile agent, see Mobile agent, page 722. If you have a security policy in place, exclude these ports from that policy so the mobile agent can operate properly. You can lock down or harden your security systems once these ports are open. Deploying the Data Security mobile agent comprises the following basic steps: 1. Installing the mobile agent software, page 342 2. Configuring the mobile agent, page 352 3. Configuring a mobile DLP policy, page 354 340 Websense Data Security Installing Data Security Components Mobile agent installations include: A policy engine Secondary fingerprint repository (the primary is on the management server) Hardware requirements The mobile agent is a soft appliance.

It receives all outbound email from the mail server and forwards it to a Websense Data Security Policy Engine. The SMTP agent then receives the analyzed email back from the policy engine. Depending on the analysis, SMTP agent blocks the email or forwards it to the mail gateway. When installed on the Data Security Management server or supplemental Data Security server, the SMTP agent uses the local policy engine of those servers to analyze email, unless load balancing has been configured, in which case it uses the specified policy engine. The SMTP agent supports permit, block, and encrypt actions. Websense recommends you use the SMTP agent whenever you want the ability to block SMTP traffic in a production environment. (If you need only monitor SMTP traffic, the protector may be a better choice for you.) Deployment and Installation Center 355 Installing Data Security Components To use the SMTP agent, you need to configure your corporate email server to route email to it. (The agent becomes a MTA, accepting responsibility for delivery of mail.) When the agent is installed on a Data Security server, the SMTP traffic is analyzed by the local policy engine. When it is installed as a stand-alone agent, email messages that are sent to the agent are sent to a Data Security server for analysis (whichever server the SMTP agent is registered with). You can configure Websense Data Security to block or quarantine flagged messages. If an SMTP email transaction was blocked or quarantined, the administrator responsible for handling this incident can release this incident to those recipients originally blocked from receiving the content. The SMTP agent is usually not the final server in the chain of custody before the email leaves the enterprise. Email is more frequently passed along to another MTA that provides additional processing (anti-virus scanning, for example). If you have multiple mail servers, you can deploy multiple SMTP agents or you can have one SMTP agent and configure load balancing between the SMTP agent and the outgoing mail server. If this is not built into your SMTP server, you can use an external load balancer to achieve this. Operating system support The server must be running on the following operating system environments: Windows Server 2003 (32-bit) Standard or Enterprise R2 Standard or Enterprise R2 SP2 Windows Server 2003 (64-bit) Standard or Enterprise R2 Required ports The following ports must be kept open for the SMTP agent: Outbound To Port Purpose Data Security Management Server 1750017515* Consecutive ports that allow communication with Websense agents and machines. Data Security Server 1750017515* Consecutive ports that allow communication with Websense agents and machines. Next hop MTA 25** SMTP for inbound/outbound traffic * This range is necessary for load balancing. ** This is default. Other port can be configured. Inbound From 356 Websense Data Security Port Purpose Installing Data Security Components Previous MTA 25* SMTP for inbound/outbound traffic * This is default. Other port can be configured. Preparing a machine for the SMTP agent The following procedure describes how to prepare a Windows 2003 Server for the Data Security SMTP agent. 1. Install Microsoft IIS with SMTP. a. In Windows control panel, select Add/Remove programs > Windows Components. b. Select Application Server, and then click Details. c. Select Internet Information Services (IIS), and then click Details. d. Select SMTP Service, and then click Details. e. Click OK 3 times to close the windows. f. Click Next to configure and install the components. 2. Configure the SMTP Service. a. In IIS Manager, right-click the Default SMTP Virtual Server and rename it to “Inbound”. b. Right-click the Inbound server and select Properties. c. Select the Messages tab, and then deselect all message “Limits”. (These should be enforced by the mail server.) d.

The printer agent supports permit and block actions. When a user on the network prints a file, it is routed to the Microsoft Windows printer spooler service, where the printer agent intercepts it and sends it to the Data Security policy engine. After analysis of the content, the Data Security system enforces the policy as necessary: either auditing, monitoring or blocking the print job from being printed, in which case the sender (the user who printed the document) receives a notification that the print job was blocked. The printer agent is capable of identifying the user that submitted the print job, because these credentials are included in the print job. Websense Data Security generates forensics reports that list the blocked print files along with other blocked transmissions. You install the printer agent on a Windows print server. It includes optical character recognition (OCR) capabilities. The OCR service enables the recognition and prevention of “corporate-defined” confidential content being printed. The OCR service is required not only to support certain sources, but is also a must when certain printer drivers are used, for example, PCL 6. As a general rule, only standard formats, such as extended meta file (EMF), printer control language (PCL), text (TXT), and Deployment and Installation Center 365 Installing Data Security Components postscript (PS) can be received by the printer agent. Nonstandard formats are not supported. The printer agent is installed using a separate printer agent package (WebsenseDataSecurityPrinterAgent.zip) See Installing the printer agent, page 367 for instructions. Operating system support The printer agent supports the following Windows Server 2003 32-bit environments: Standard or Enterprise Standard or Enterprise R2 Standard or Enterprise R2 SP2 Required ports The following ports must be kept open for the printer agent: Outbound To Port Purpose Data Security Management Server 443 Secure communications 366 Websense Data Security Installing Data Security Components Data Security Management Server 1750017515* Consecutive ports that allow communication with Websense agents and machines.

Inbound None Prerequisites There are 2 prerequisites for installing the Data Security printer agent: The computer where you’re installing the agent must be inside a domain. The computer where you’re installing the agent must have at least one printer already installed. For best practice, do not install the printer agent on the same machine as a supplemental Data Security Server in a production environment. If these 2 conditions are not met, the installer doesn’t show the option to install the printer agent. Installing the printer agent 1. Download and extract WebsenseDataSecurityPrinterAgent.zip from mywebsense.com on the print server machine. 2. Launch the Data Security installer, DSS-7.7.0.60-x86.msi, on the print spooler machine. Your version and build number may vary. 3. On the Welcome screen, click Next to begin the installation. 4. In the Destination Folder screen, specify the folder into which to install the agent. The default destination is C:\Program Files or Program Files (x86)\Websense\Data Security. If you have a larger drive, it is used instead. Large removable drives may be detected by the system as a local drive and used as the default. Do not install on removable media. Important The full installation path must use only ASCII characters. Do not use extended ASCII or double-byte characters. Deployment and Installation Center 367 Installing Data Security Components Note Regardless of what drive you specify, you must have a minimum of 0.5 GB of free disk space on the C: drive.

On the Select Components screen, select Printer Agent and then Entire feature will be installed on local hard drive. 6. When prompted, click Setup to extract a software installer for GPL Ghostscript. Ghostscript is an interpreter for .ps and .pdf description languages. This software is required for the printer agent. 7. Accept the defaults in the Ghostscript wizard, then click Install. 8. The Optical Character Recognition screen appears. Section Description OCR Analysis Threshold Per printed page: This parameter limits dynamically (according to the number of pages) the total time that the OCR can extract textfrom the printed job. In case of a timeout, the content analysis will be performed only on the extracted text that took place before the timeout. (Default value: 3 sec.; Range: 1-60 sec.) No more than nn seconds: This number is a static overall limit to the total time that the OCR can extract text from the printed job. In case of a timeout, the content analysis will be performed only on the extracted text that took place before the timeout. (Default value: 300 sec.; Range: 1-3600 sec.) OCR Accuracy Running the OCR in accurate mode results in higher latency. Administrators can set the size of jobs that will be executed in the most accurate OCR mode (small jobs do not produce high latency, so it is reasonable to use better accuracy). In most cases, lower OCR quality is sufficient and provides good results. Keep in mind that the average OCR Analysis per printed page limit is ignored for small documents, but the entire print job limit is still adhered to. (Default value: 5 pages) Optionally, you can change the default values defined for the OCR Analysis Threshold and the OCR Accuracy. 9. The Fingerprinting Database screen appears. To choose a location other than the default shown, use the Browse button. 10.

Add a parameter to the [RecognizerParams] section as follows: 370 Websense Data Security Installing Data Security Components [RecognizerParams] TextLanguage = English,French 6. Save the *.ini files. Printer agent performance The printer agent has different demand levels, depending on whether it is in Monitoring or Blocking mode, and whether the OCR service is activated or deactivated. Monitoring mode operates in an asynchronous manner and therefore, does not introduce analysis time overhead to the printing time. In Blocking mode, the OCR processing adds up to 3 seconds per page depending on the CPU power of the printer server. You can select Blocking or Monitoring in the Edit Printer Agent window, accessed through Settings > Deployment > System Modules. Select the printer agent on the System Modules screen. Select Monitoring if you want to monitor traffic through the print server but not block it. Select Blocking if you want to block actions that breach policy. Deployment and Installation Center 371 Installing Data Security Components Integration agent Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.7.x In this topic: Installing the integration agent, page 372 Registering the integration agent, page 373 Using the Websense Data Security API, page 374 The integration agent allows third-party products to send data to Websense Data Security for analysis. Third parties can package the integration agent inside their own installer using simple, 'industry standard' methods that are completely transparent to end users. When the third-party product is installed on a users system, it needs to register the integration agent with the Data Security Management Server. This can be done transparently through the installation process or using a command-line utility. The integration agent works on the following operating systems: Windows Server, 32-bit Redhat Enterprise Linux TRITON - Data Security treats third-party products that use the integration agent as it does any other agent. It supports all relevant views and capabilities, including: Incident Management and Reporting Quarantine and Release of emails Traffic log view Load balancing capabilities The Integration agent does not support discovery transactions. For information on configuring the integration agent, see “Configuring the integration agent” in the TRITON - Data Security Help system. Installing the integration agent Installed components When you embed the integration agent in your product installer, 3 Data Security components are installed on the end-user machine: 372 Websense Data Security Installing Data Security Components PEInterface.dll - A DLL the that interacts with the Data Security policy engine on the management server. ConnectorsAPIClient.exe - Client software that connects the API in the thirdparty product with Websense Data Security. registerAgent.bat (or .vbs) - A script that performs registration with the Data Security Management Server. Installation package format On Windows, the installation package for the integration agent is provided in 2 major formats: MSM file. The installer that uses the MSM can choose (by setting properties) whether or not to register the product with the Data Security Management Server during installation. The MSM contains a 'custom action' that validates Data Security user names and passwords and can be called by the third-party installer. MSI file. This file embeds the MSM file. Some parties prefer to work with an MSI, and others can use it as a reference implementation. The MSI installation wizard presents 4 interactive dialogs: Installation-dir - installation directory. Registered Channels - The DLP channels to use: HTTP, SMTP, Printer, Discovery. Local IP Address - which of the static IP addresses currently assigned to the machine should be used for registration. Data Security Management Server details - IP address or host name, user name, password. On Linux, the package is in the form of a relocatable RPM. Registering the integration agent Every instance of the integration agent needs to be registered after being installed. (This is a one time operation.) In other words, every time the third-party product is installed on an end-user machine, that instance of the agent needs to be registered. The registration operation can be done during the installation by the installer, or using a command-line utility provided with the agent. The command-line utility should receive the following input arguments: Protocols - a non-empty list of supported protocols (out of HTTP, SMTP, Printer, Discovery). Data Security Management Server details - IP address or host name, user name, password. Local IP Address (optional) - In case this is not supplied, use any of the static addresses of the machine, and print it to the standard output. Deployment and Installation Center 373 Installing Data Security Components Search IP Address (optional) - used for re-registration after IP change. In case this is not supplied, use the address in the registerAgent.conf file. If that file does not exist, use the given local IP address. A successful operation registers the machine with the Data Security Management Server as having the desired protocols and generates certificate files in the same directory that the tool is located. The tool also stored a configuration file (registerAgent.conf) with the IP address used for registration. On failure, the script returns a meaningful exit code and prints an error message to standard output Using the Websense Data Security API Third parties that subscribe to the integration agent use a C-based API to send data to Websense Data Security for analysis and receive dispositions in return. The API can be used to configure analysis operations on a transaction-by-transaction basis on the following variables: Channel/Protocol - Upon installation the third-party product can declare its ability to intercept various protocols, and assign each transaction to a protocol. Blocking/Monitoring mode - each transaction can work in a different mode. Timeout - can be different per transaction. For documentation on the Data Security API, consult with your Websense Sales representative. 374 Websense Data Security Installing Data Security Components The crawler Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: In this topic: Data Security, v7.7.x Operating system support, page 375 Required ports, page 375 Installing the crawler agent, page 376 The crawler is the name of the discovery and fingerprinting agent.

Below are how to resolve common problem scenarios. Initial registration fails Make sure you can ping the Data Security agents by IP and by host name from the TRITON Management Server. On Windows, run the following command (in a Command Prompt) to check for block ports: netstat 1 -na | find "SYN" Each line displayed in response to the command is a blocked port. This command is one-way. Run it on both the agent machine and the TRITON Management Server. Check logs on the TRITON Management Server (and remote policy engines). %dss_home%/logs/mgmtd.log %dss_home%/tomcat/logs/dlp/dlp-all.log Check logs on the protector. These reside in the /opt/websense/neti/log directory. In particular, check: /opt/websense/neti/log/registration.log Make sure no duplicate certificates are installed on the agents’ servers; if there are duplications, delete all of them and re-register the agent. Also, make sure the system date/time of the agent machine and the TRITON Management Server are the same. The following certificates are expected: Certificate > My User Account > Trusted Root Certification Authorities > Certificates > ws-ilp-ca Certificates > Computer > Personal Certificates ><servername>(issued by ws-ilp-ca) Certificates > Computer > Trusted Root Certification Authorities > Certificates > ws-ilp-ca Deployment and Installation Center 379 Installing Data Security Components Make sure the FQDN value of the agent states the full server name for the agent’s server. Protector — if domain name is configured, the FQDN is: protectorname.domain.name Agents and Data Security server — check “My Computer” properties and copy the computer name value from there. Deploy settings fails Make sure you can ping the agents by IP and by host name from the TRITON Management Server. Check logs on the TRITON Management Server (and remote policy engines). %dss_home%/tomcat/logs/dlp/dlp-all.log %dss_home%/tomcat/logs/dlp/deployment-trace.log Check the plat.log on the protector. Subscription errors Restart the Websense TRITON - Data Security service on the TRITON Management Server. Check %dss_home%/tomcat/logs/dlp/dlp-all.log. Network connectivity problems In complex networks, network connectivity may require routes added to the inline protector. Although routes can be added with the built in kernel route command, it is strongly recommended that the /opt/websense/neti/bin/route command is used instead. If the kernel route (/sbin/route) is used, the added routes will be lost after rebooting. /opt/websense/neti/bin/route writes the routes to a file /opt/pa/conf/route so that on subsequent reboots the route information is re-submitted to the protector.

Installing TRITON Infrastructure Deployment and Installation Center | Web, Data, and Email Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Data Security, v7.7.x Email Security Gateway and Gateway Anywhere, v7.7.x TRITON Infrastructure is composed of common user interface, logging, and reporting components required by the TRITON Unified Security Center modules (TRITON Web Security, TRITON - Data Security, and TRITON - Email Security). 386 Websense TRITON Enterprise Installing components via the Custom option When installing TRITON Infrastructure, you can choose to also install SQL Server 2008 R2 Express—a free, limited-performance version of SQL Server—to be used for Websense logging data. It is important to note that, as a best practice, SQL Server 2008 R2 Express should be used only in non-production or evaluation environments. A non-limited-performance version of SQL Server should be used in production environments. 1. It is assumed you have already launched the Websense installer done one of the following: Selected the Custom installation type, and selected TRITON Infrastructure install. (See Deployment, page 383.) Selected the TRITON Unified Security Center installation type. (See Installing TRITON Unified Security Center, page 181.) Started an upgrade of prior-version Web or Data Security components, with TRITON - Web Security or Data Security installed on this machine. In this case, skip to Step 3 now. 2. On the Custom Installation dashboard, click the Install link for TRITON Infrastructure. (If TRITON Infrastructure Setup has been started as part of a TRITON Unified Security Center installation, skip this step.) TRITON Infrastructure Setup is launched. 3. On the TRITON Infrastructure Setup Welcome screen, click Next. 4. On the Installation Directory screen, specify the location where you want TRITON Infrastructure to be installed and then click Next. Important The full installation path must use only ASCII characters. Do not use extended ASCII or double-byte characters. Deployment and Installation Center 387 Installing components via the Custom option To accept the default location (recommended), simply click Next. To specify a different location, click Browse. 5. On the SQL Server screen, specify the location of your database engine and the type of authentication to use for the connection. Also specify whether to encrypt communication with the database. The information entered here is also used by the Web, Data, and Email Security component installers, by default. The Web Security component installer can be used to specify a different database; the Data and Email Security component installers cannot. Select Use existing SQL Server on this machine if the Websense installer has already been used to install SQL Server 2008 R2 Express on this machine. Select Install SQL Server Express on this machine to install SQL Server 2008 R2 Express on this machine. When this option is selected, .NET 3.5 SP1, Powershell 1.0, and Windows Installer 4.5 are installed automatically if they are not found on the machine. These are required for SQL Server 2008 R2 Express. A default database instance named mssqlserver is created, by default. If a database instance with the default name already exists on this machine, an instance named TRITONSQL2K8R2X is created instead. If .NET 3.5 SP1 is not found on the machine, the installer needs access to windowsupdate.microsoft.com. If anything blocks this machine from accessing the site, SQL Server Express cannot be installed. If you currently use MSDE for Websense data and want to use that data postupgrade, back up the Websense before installing SQL Server 2008 R2 Express (see Backing up the MSDE Log Database, page 766). Leave the Websense installer running and come back once you have backed up MSDE data. In some cases, you are prompted to reboot the machine after installing SQL Server Express. If you do, go to Start > All Programs > Websense > Websense TRITON Setup to restart the installer. Select Use existing SQL Server on another machine to specify the location and connection credentials for a database server located elsewhere in the network. Enter the Hostname or IP address of the SQL Server machine, including the instance name, if any. • • If you are using a named instance, the instance must already exist. If you are using SQL Server clustering, enter the virtual IP address of the cluster. Also provide the Port used to connect to the database (1433, by default). See System requirements for this version, page 2, to verify your version of SQL Server is supported. After selecting one of the above options, specify an authentication method and account information: 388 Websense TRITON Enterprise Installing components via the Custom option Select the Authentication method to use for database connections: SQL Server Authentication (to use a SQL Server account) or Windows Authentication (to use a Windows trusted connection). Next, provide the User Name or Account and its Password. This account must be configured to have system administrator rights in SQL Server. If you are using SQL Server Express, sa (the default system administrator account) is automatically specified (this is the default system administrator account). For more information about permissions required for the connection account, see Installing with SQL Server, page 411. If you use a trusted account, an additional configuration step is required after installation to ensure that reporting data can be displayed in TRITON - Web Security and its reporting tools. See Using a batch file for Apache SSL certificate file operations, page 728. When you click Next, connection to the database engine is verified. If the connection test is successful, the next installer screen appears. If the test is unsuccessful, the following message appears: Unable to connect to SQL Make sure the SQL Server you specified is currently running. If it is running, verify the access credentials you supplied. Click OK to dismiss the message, verify the information you entered, and click Next to try again. 6. On the Server & Credentials screen, select the IP address of this machine and specify network credentials to be used by TRITON Unified Security Center. Select an IP address for this machine. If this machine has a single network interface card (NIC), only one address is listed. Use the IP address selected to access the TRITON Unified Security Center (via Web browser). Also specify this IP address to any Websense component that needs to connect to the TRITON management server. If you chose to install SQL Server 2008 R2 Express, if you install Web Security or Email Security Log Server on another machine, specify this IP address for the database engine location. Specify the Server or domain of the user account to be used by TRITON Infrastructure and TRITON Unified Security Center. The server/host name cannot exceed 15 characters. Specify the User name of the account to be used by TRITON Unified Security Center. Enter the Password for the specified account. If you are installing Data Security v7.7.0, this password must not exceed 19 characters. If you are installing version 7.7.2 or beyond, password length doesn’t matter. 7. On the Administrator Account screen, enter an email address and password for the default TRITON console administration account: admin. When you are finished, click Next. System notification and password reset information is sent to the email address specified (once SMTP configuration is done; see next step). Deployment and Installation Center 389 Installing components via the Custom option It is a best practice to use a strong password as described onscreen. 8. On the Email Settings screen, enter information about the SMTP server to be used for system notifications and then click Next. You can also configure these settings after installation in the TRITON console. Important If you do not configure an SMTP server now and you lose the admin account password (set on previous screen) before the setup is done in the TRITON console, the “Forgot my password” link on the logon page does not provide password recovery information. SMTP server configuration must be completed before password recovery email can be sent. IP address or hostname: IP address or host name of the SMTP server through which email alerts should be sent. In most cases, the default Port (25) should be used. If the specified SMTP server is configured to use a different port, enter it here. Sender email address: Originator email address appearing in notification email. Sender name: Optional descriptive name that can appear in notification email. This is can help recipients identify this as a notification email from the TRITON Unified Security Center. 9. On the Pre-Installation Summary screen, verify the information and then click Next to begin the installation.

On Linux, NICs without an IP address are also listed. Do not choose a NIC without an IP address. After installation, you can configure Network Agent to use NICs without an IP address to monitor Internet requests. See Network Agent and stealth mode NICs, page 685. Note For Network Agent to operate, this machine must be connected to a bi-directional span port (or mirror port) on a switch or hub that processes the network traffic to be monitored. Deployment and Installation Center 403 Installing components via the Custom option You may select multiple NICs. After installation, use TRITON - Web Security to configure how Network Agent will use each selected NIC (for more information, see the TRITON - Web Security Help). Database Information Screen Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x This Web Security installer screen appears if Web Security Log Server is selected for installation and TRITON Infrastructure is not installed on this machine. Enter the hostname or IP address of the machine on which a supported database engine is running (see System requirements for this version, page 2, for supported database system information). If a supported database engine is detected on this machine, its IP address is already entered by default. To use a database engine on a different machine, enter its IP address instead. If you are using SQL Server clustering, enter the virtual IP address of the cluster. After entering the IP address of the database engine machine, choose how to connect to the database: Select Trusted connection to use a Windows account to connect to the database. Enter the user name and password of a trusted account with local administration privileges on the database machine. Note that the trusted account you specify here should be the same as that with which you logged onto this machine before starting the Websense installer. If you use a trusted account, an additional configuration step is required after installation to ensure that reporting data can be displayed in TRITON - Web Security and its reporting tools. See Using a batch file for Apache SSL certificate file operations, page 728 Select Database account to use a SQL Server account to connect to the database. Enter the user name and password for a SQL Server account that has administrative access to the database. The SQL Server password cannot be blank, or begin or end with a hyphen (-). Note The database engine must be running to install Websense reporting components. The installer will test for a connection to the specified database engine when you click Next on the Database Information screen. The installer cannot proceed unless a successful connection can be made. 404 Websense TRITON Enterprise Installing components via the Custom option Log Database Location Screen Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x This Web Security installer screen appears if Web Security Log Server is selected for installation. Accept the default location for the Log Database files, or select a different location. Then, click Next. Note that if TRITON Infrastructure is installed on this machine, the default database location information is taken from TRITON Infrastructure’s configuration. Typically, you should accept the default in this case. If the database engine is on this machine, the default location is the Websense directory (C:\Program Files (x86)\Websense). If the database engine is on another machine, the default location is C:\Program Files\Microsoft SQL Server on that machine. It is a best practice to use the default location. If you want to create the Log Database files in a different location (or if you already have Log Database files in a different location), enter the path. The path entered here is understood to refer to the machine on which the database engine is located. Important The directory you specify for the Log Database files must already exist. The installer cannot create a new directory. You can also specify a particular database instance in this path. The instance must already exist. See Microsoft SQL Server documentation for information about instances and paths to instances.

If you enter a hostname, itmust be in the form of a fully-qualified domain name: machine_name.domain_name Remember whether you entered an IP address or a hostname here. When installing Remote Filtering Client on user machines, you must enter this address in the same form (IP address or name). It is a best practice to use IP addresses, rather than hostnames, unless you are confident of the reliability of your DNS servers. If hostnames cannot be resolved, Remote Filtering Clients cannot connect to Remote Filtering Server. The external communication port can be any free port in the range 10-65535 on this machine. This port receives HTTP/HTTPS/FTP requests from external Remote Filtering Client machines (i.e. user machines, running Remote Filtering Client, outside the network). The default is 80. If a Web server is running on this machine, it may be necessary to use a different port. Note The external network firewall or gateway must be configured to route traffic, typically via PAT or NAT, from Remote Filtering Client machines to the internal IP address of this machine. The internal communication port can be any free port in the range 1024-65535 on this machine. The default is 8800. This is the port to which remote client heartbeats are sent to determine whether a client machine is inside or outside the network. The 408 Websense TRITON Enterprise Installing components via the Custom option external network firewall must be configured to block traffic on this port. Only internal network connections should be allowed to this port. For more information, see the Remote Filtering Software technical paper. Remote Filtering Pass Phrase Screen Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x This screen appears if Remote Filtering Server is selected for installation. The pass phrase can be any length. This pass phrase is combined with unpublished keys to create an encrypted authentication key (shared secret) for secure client/server communication. If you want this instance of Remote Filtering Server to function as a backup (secondary or tertiary) server for a primary Remote Filtering Server, you must enter the same pass phrase used when installing the primary Remote Filtering Server. The pass phrase must include only ASCII characters, but cannot include spaces. Do not use extended ASCII or double-byte characters. You must use this pass phrase when you install the Remote Filtering Client on user machines that will connect to this Remote Filtering Server. Filtering Service Information for Remote Filtering Screen Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x This Web Security installer screen appears if Remote Filtering Server is selected for installation. Internal IP address: Enter the actual IP address of the Filtering Service machine to be used by this instance of Remote Filtering Server. Filtering port and Block page port: The filtering port is used by Filtering Service to communicate with other Websense components.

Deployment and Installation Center 413 Installing components via the Custom option Installing Email Security components Deployment and Installation Center | Email Security Solutions | Version 7.7.x Applies to: Email Security Gateway and Gateway Anywhere, v7.7.x Websense Email Security Gateway is an appliance-based solution. All components run on the appliance except TRITON - Email Security (i.e., the Email Security module of the TRITON Unified Security Center) and Email Security Log Server. These are the only two Email Security components that may be installed using the Websense installer. 1. It is assumed you have already launched the Websense installer and chosen the Custom installation type. If not, see Deployment, page 383. 2. On the Custom Installation dashboard, click the Install link for Email Security. 3. The Email Security component installer is launched. 4. On the Introduction screen, click Next. 5. If the Email Security Installer detects TRITON Infrastructure on this machine, it operates as if it is part of a TRITON Unified Security Center installation. See Installing TRITON - Email Security, page 190, for instructions. If TRITON Infrastructure is not detected, then the Email Security Installer operates in custom mode. 6. In the Select Components screen specify whether you want to install Email Security Log Server. 414 Websense TRITON Enterprise Installing components via the Custom option Email Security Log Server is selected for installation by default. To install Email Security Log Server, SQL Server or SQL Server Express must already be installed and running in your network. (See System requirements for this version, page 2, for supported database systems.) If you choose to install Email Security Log Server, the Email Security Log Server Configuration utility is also installed. This utility can be accessed by selecting Start > All Programs > Websense > Email Security > Email Security Log Server Configuration. 7. If TRITON Infrastructure is not found already installed on this machine, the Email Security Database screen appears. Specify the location of a database engine and how you want to connect to it. Log Database IP: Enter the IP address of the database engine machine. If you want to use a named database instance, enter it the form <IP address>\<instance name>. Note that the instance must already exist. See your SQL Server documentation for instructions on creating instances. If you chose to install SQL Server Express as part of the installation of the TRITON Unified Security Center, the log database IP address should be that of the TRITON Unified Security Center machine. You may specify whether the connection to the database should be encrypted. Please note the following issues associated with using this encryption feature: • • • You must have imported a trusted certificate to the Log Server machine in order to use the encryption option. See your database documentation for information about importing a trusted certificate. The Bulk Copy Program (BCP) option for inserting records into the Log Database in batches cannot be used. Not using the batch method may affect Log Database performance. The connection from the Email Security module on the TRITON Console to the V-Series appliance cannot be encrypted. If you enable encryption for Log Database, you must disable the SQL Server force encryption feature. Database login type: Select how Email Security Log Server should connect to the database engine. • Trusted connection: connect using a Windows trusted connection. • Database account: connect using a SQL Server account. Then enter a user name and password. • If using a trusted connection, enter the domain\username of the account to be used. This account must be a trusted local administrator on the database engine machine. • If using a database account, enter the name of a SQL Server account. This account must have certain roles assigned; see Installing with SQL Server, page 411. When you click Next, connection to the database engine is verified. If the connection test is successful, the next installer screen appears. 8. On the Email Security Database File Location screen, specify where Email Security database files should be located and then click Next. This screen appears only if you chose to install Email Security Log Server. Deployment and Installation Center 415 Installing components via the Custom option A default location for the Log Database is automatically shown. Information about the location of the database engine and connection credentials were entered when TRITON Infrastructure was installed on this machine. The Email Security Installer reads this information from configuration files created by TRITON Infrastructure Setup. It is a best practice to use the default location. However, if you want to create the Log Database in a different location (or if you already have a Log Database in a different location), enter the path to the database files. The path entered here is understood to refer to the machine on which the database engine is located. The path entered must specify a directory that already exists. If any Email Security components (e.g., TRITON - Email Security or another instance of Email Security Log Server) have already been installed in your deployment, the following message appears: The Email Security database exists, do you want to remove it? This occurs because the database was created upon installation of the other Email Security components. Click No to continue using the existing database. In general, you should keep the database if you are sure the database was created only during the course of installing other components in your current deployment. Clicking Yes removes the database. Warning If any Email Security log data has been written to the database it will be lost if you remove the database. If you want to keep this data, back up the esglogdb76 and esglogdb76_n databases. See your SQL Server documentation for backup instructions. Warning If you remove the database, any currently quarantined email will no longer be accessible. 9. On the Installation Folder screen, specify the location to which you want to install Email Security Log Server and then click Next. Important The full installation path must use only ASCII characters. Do not use extended ASCII or double-byte characters. To select a location different than the default, use the Browse button. Email Security Log Server will be installed in its own folder under the parent folder you specify here. 10. On the Pre-Installation Summary screen, review the components to be installed. If they are correct, click Install. 416 Websense TRITON Enterprise Installing components via the Custom option 11.

Installing SQL Server 2008 R2 Express (without TRITON Infrastructure) Deployment and Installation Center | Web, Data, and Email Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Data Security, v7.7.x Email Security Gateway and Gateway Anywhere, v7.7.x During TRITON Infrastructure installation, you can choose to install SQL Server 2008 R2 Express along with it. If you are installing TRITON Infrastructure, and you want to install SQL Server 2008 R2 Express on the same machine (i.e., the TRITON management server) you should do so during TRITON Infrastructure installation. See Installing TRITON Infrastructure, page 386. This section provides instructions for installing SQL Server 2008 R2 Express without installing TRITON Infrastructure. Typically, this is done to install SQL Server 2008 R2 Express on a machine that is not a TRITON management server. 1. If you will use SQL Server 2008 R2 Express to store and maintain Web Security data, log in to the machine as domain user. Do this prior to starting the Websense installer. 2. It is a best practice to install the Windows prerequisites for installing SQL Server Express beforehand: .NET Framework 3.5 SP1 Powershell 1.0 Windows Installer 4.5 Note The Websense installer will automatically install these if not found on the machine. See SQL Server 2008 R2 Express, page 16. Deployment and Installation Center 417 Installing components via the Custom option 3. If you currently use MSDE for Websense data and want to use that data postupgrade, back up the Websense databases now. See Backing up the MSDE Log Database, page 766, for instructions. Leave the Websense installer running and come back once you have backed up MSDE data. You may have to stop Filtering Service now. If .NET 3.5 SP1 is not found on this machine, the installer needs access to windowsupdate.microsoft.com. If Filtering Service blocks this machine from accessing windowsupdate.microsoft.com SQL Server Express cannot be installed. 4. It is assumed you have already launched the the Websense installer and chosen the Custom installation type. If not, see Starting a custom installation. You may also be following these instructions as part of upgrading (Web Security) Log Server to version 7.6. If so, skip this step. Also note that instead of the Custom Installation dashboard, you may be in the Modify Installation dashboard. The steps to complete remain the same. 5. On the Custom Installation dashboard, click the Install link for SQL Server Express. 6. On the Welcome screen, click Start to begin the installation wizard. 7. On the Configuration screen, selection options as described below and then click Next. Use the Browse button to specify a different folder if you do not want to install to the default location shown. If you want to create a named instance, instead of using the default SQL Server instance, select Named instance and then enter an instance name. Note the following about instance names: Note If MSDE is currently installed on this machine, you must install SQL Server Express to a named instance. It is a best practice to name the instance TRITONSQL2K8R2X. Other upgrade instructions regarding moving Websense data from MSDE to SQL Server Express will assume this instance name if both are installed on the same machine. If you choose a different one, substitute the instance name accordingly when following those instructions. • • • • • Not case sensitive 16 characters or less Only letters, numbers, dollar sign ($), or underscore (_) are allowed First character must be a letter Cannot contain the term Default or other reserved keyword (see Microsoft documentation for more information about reserved keywords) Select an authentication mode: • Windows Authentication mode: select this to use Windows authentication, i.e., trusted connection, to authenticate users. 418 Websense TRITON Enterprise Installing components via the Custom option • Mixed Mode (SQL Server authentication and Windows authentication): select this to use SQL Server authentication.

Deployment and Installation Center 419 Installing components via the Custom option 420 Websense TRITON Enterprise 18 Installing and Deploying Websense Endpoint Clients Deployment and Installation Center | Web and Data Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x Data Security, v7.7.x In this topic When to use Web Endpoint, page 422 When to use the Remote Filtering Client, page 422 When to use Data Endpoint, page 423 Endpoint solution system requirements, page 423 Websense, Inc., offers solutions for securing client workstations, laptops, and other endpoint devices from data loss and inbound Web threats when the devices are outside the corporate network. The solutions are endpoint client software applications that run on the endpoint devices to block, monitor, and log transactions (like Internet requests) according to the organization’s security and acceptable use policies. Administrators can create policies that provide full visibility into inbound and outbound traffic, but that don’t restrict use of the device. For Web security, the endpoint clients are: Remote Filtering Client (see When to use the Remote Filtering Client, page 422) Websense Web Endpoint (see When to use Web Endpoint, page 422) And for data loss prevention (DLP): Websense Data Endpoint (see When to use Data Endpoint, page 423) Websense endpoint solutions include both server and client components. See System requirements for this version, page 2, for information about the hardware requirements and supported operating systems for endpoint components. Deployment and Installation Center 421 Installing and Deploying Websense Endpoint Clients When to use the Remote Filtering Client Remote filtering software can be used with any Web Security solution to manage Internet activity for endpoint devices (client machines) outside the network. Remote filtering software has 2 components: Remote Filtering Client and Remote Filtering Server. Remote Filtering Client is installed on each endpoint device (client machine). Warning Remote Filtering Client cannot be installed on machines running Remote Filtering Server. That combination eventually causes filtering to fail. Important In Web Security Gateway Anywhere deployments, Remote Filtering Client cannot be used on machines filtered by the hybrid service. Remote Filtering Server resides inside the network, and acts as a proxy to Websense Filtering Service. Internet requests from clients using remote filtering software are processed as follows: 1. Remote Filtering Client routes Internet requests to Remote Filtering Server. 2. Remote Filtering Server forward the requests to Websense Filtering Service. 3. Filtering Service determines whether to block or permit the request. 4. Filtering Service sends the block or permit response to Remote Filtering Server. 5. Remote Filtering Server responds to Remote Filtering Client. All communication between the client and server is authenticated and encrypted. By default, the remote filtering software manages all HTTP, HTTPS, and FTP requests from machines where Remote Filtering Client is installed. Remote filtering software can apply a user, group, or OU policy to a request, or the Default policy. (IP-address-based policies, applied to the computer or network, cannot be applied to machines when they are outside the network.) When to use Web Endpoint In Websense Web Security Gateway Anywhere deployments, Websense Web Endpoint can be used to secure client machines whose Internet activity is managed by the hybrid service. Web Endpoint provides transparent authentication and enforces the use of hybrid Web security policies. Web Endpoint routes Internet requests to the hybrid service so that the appropriate Web security policy can be applied. 422 Choosing and Deployment Data Security Agents Installing and Deploying Websense Endpoint Clients Web Endpoint has 2 operation modes: In Web scanning and filtering mode, the endpoint client redirects HTTP and HTTPS traffic to the hybrid service with an encrypted token that identifies the user, enabling the correct policy to be applied and reporting data to be correctly logged. No password or other security information is included. The endpoint client can be used with both full-tunnel and split-tunnel VPNs, ensuring that all Web traffic is scanned and filtered. In proxy manipulation mode, for supported browsers, the endpoint client manipulates proxy settings in real time. For example, if the endpoint detects it is at a hotspot, but the user has not finished registration, it removes its proxy settings until the gateway has successfully opened. You can enable Web Endpoint for some or all machines filtered by the hybrid service. When to use Data Endpoint Data Endpoint is designed for organizations concerned about data loss originated at the endpoint, whether malicious or inadvertent. For example, if you want to prevent employees from taking sensitive data home on their laptops and printing it, posting to the Web, copy and pasting it, etc., you would benefit from this endpoint solution. Websense Data Endpoint is a comprehensive, secure and easy-to-use endpoint data loss prevention (DLP) solution. It monitors real-time traffic and applies customized DLP policies over application and storage interfaces. You can also apply discovery policies to endpoints to determine what sensitive data they hold. You can monitor user activity inside endpoint applications, such as the cut, copy, paste, print, and print screen operations. You can also monitor endpoint Web activities and know when users are copying data to external drives and endpoint devices. Endpoint solution system requirements System requirements for this version, page 2, provides the operating system requirements for endpoint server and client components. Find Web security requirements under “Web Security and Web Security Gateway,” in the “Software deployments,” “Client OS,” and “Web endpoint” sections. Find data security requirements under “Data Security,” in the “Operating system” and “Data Endpoint hardware requirements” sections. Deployment and Installation Center 423 Installing and Deploying Websense Endpoint Clients Deploying Websense endpoints Deployment and Installation Center | Web and Data Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Creating installation packages, page 425 Deployment options, page 436 Data Security, v7.7.x There are different methods for configuring and packaging endpoint client software depending on which endpoint client or combination of clients you are using: When Web Endpoint is installed by itself on client machines, use the endpoint package provided on the Settings > Hybrid Configuration > Hybrid User Identification page in TRITON - Web Security. Different endpoint packages are available for 32-bit and 64-bit clients; select the appropriate package (or combination of packages) from the list provided. When you select an endpoint package, a GPO command is displayed on the page. Use the command provided if you intend to deploy the Web Endpoint MSI package to client machines via GPO. See the TRITON - Web Security Help for more information about downloading and deploying Web Endpoint. When Web Endpoint is installed with Data Endpoint, use the Websense Endpoint Package Builder (see below) to create a combined installation package for both the Web and Data Endpoints. The combined installation package (a single executable file) is used to deploy both endpoint clients to user machines. When Remote Filtering Client or Data Endpoint is installed alone, or when the two endpoint clients are installed together, use the Websense Endpoint Package Builder (see below) to create an installation package. The Endpoint Package Builder is a Windows utility that can be used to create 32- and 64-bit Windows packages for Remote Filtering Client, Web Endpoint, and Data Endpoint. It can also be use to create Linux packages for Data Endpoint. The utility can run on any Windows machine to create or configure Remote Filtering Client installation packages. The utility must run on a machine with Data Security components installed to create or configure Data Endpoint packages. 424 Choosing and Deployment Data Security Agents Installing and Deploying Websense Endpoint Clients The package builder can be found in the following directories: If Web Security is installed: C:\Program Files or Program Files (x86)\Websense\Web Security\DTFAgent\RemoteFilteringAgentPack\ If Data Security is installed: C:\Program Files or Program Files (x86)\Websense\Data Security\client\ Creating installation packages Note If you existing versions of Data Endpoint or Remote Filtering Client are running on client machines, uninstall them before deploying the new installation packages. 1. To launch the Websense Endpoint Package Builder: On any Windows server that includes Web Security components, navigate to C:\Program Files or Program Files (x86)\Websense\Web Security\DTFAgent\RemoteFilteringAgentPack and double-click WECfg.exe. If you don’t want to run the package builder on the server machine, copy the executable to another Windows machine (server or workstation) and run the executable there. On the Data Security Management Server machine, navigate to Start > All Programs > Websense > Data Security > Endpoint Package Builder. The Websense Endpoint Package Builder utility extracts required files and launches. Deployment and Installation Center 425 Installing and Deploying Websense Endpoint Clients 2. On the Select Components screen, select one or more endpoint clients to configure. You can create packages for both Websense Data Endpoint and one Web Security endpoint client, but you cannot select both Remote Filtering Client and Web Endpoint at the same time. Also select a language for the client components. In the TRITON Console, you can change the language used for displaying messages to Data Endpoint users, but the language displayed in the user interface (buttons, captions, fields, etc.) can only be set during packaging. Click Next when you’re done. 426 Choosing and Deployment Data Security Agents Installing and Deploying Websense Endpoint Clients 3. On the Installation Platform and Security screen, select the operating system or systems for which you want to create an installation package, create the administrator password that will be used to uninstall or modify endpoint client software, and configure anti-tampering settings. When you are finished, click Next. You can create Windows (32-bit or 64-bit) installation packages for any endpoint client. For Data Endpoint, you can also create a Mac OS X or Linux installation package. For security purposes, anyone who tries to modify or uninstall endpoint software is prompted for a password. For Web Endpoint and Data Endpoint, once the endpoint client contacts the server, this password is overwritten with the password specified by a TRITON administrator. • Data Endpoint: Administrators can set this password on the General tab under Settings > General > System > Endpoint. • Web Endpoint: Go to Settings > Hybrid Configuration > Hybrid User Identification, then enter and confirm an anti-tampering password. If no password is specified, every user is able to uninstall the endpoint software from their computer. Click Show characters to display the password characters while you type. Sometimes when users cannot modify or uninstall the endpoint software, they try to delete the directory where the software is installed. Click Protect installation directory from modification or deletion if you do not want users to be able to perform these functions. Deployment and Installation Center 427 Installing and Deploying Websense Endpoint Clients 4. On the Installation Path screen appears, specify the directory to use for installing endpoint software on each endpoint device. The directory path must contain only English characters.

When you are finished, click Next. IP address or hostname: Internal IP address or FQDN for the Remote Filtering Server machine. Port: Internal communication port on the Remote Filtering Server that can be accessed only from inside the network firewall. This must be the same port entered in the Internal Communication Port field when this Remote Filtering Server was installed. Because some machines, like laptops, may travel in and out of your organization’s network, Remote Filtering Client uses this internal connection information to determine whether it is within or outside the network. This ensures that the machine is not double filtered (by both internal Web Security components and remote filtering software). 432 Choosing and Deployment Data Security Agents Installing and Deploying Websense Endpoint Clients 2. On the External Connections screen, provide external connection details for each Remote Filtering Server that may handle requests for Remote Filtering Client instances. When you are finished, click Next. IP address or hostname: Externally visible IP address or fully qualified domain name (FQDN) of the primary Remote Filtering Server machine. Important You must use the same address format (either IP address or FQDN) as when you installed this Remote Filtering Server. Port: Externally accessible port used to communicate with the primary Remote Filtering Server. This must match the external port number entered when installing the primary Remote Filtering Server. Clear the Log user Internet activity check box to avoid recording Internet request data for machines running Remote Filtering Client. By default, Internet activity handled by Remote Filtering Client is logged for use in Web Security reporting tools. This is the information that Remote Filtering Client uses to pass Internet requests to Remote Filtering Server when the client machine (endpoint device) is outside the network. Deployment and Installation Center 433 Installing and Deploying Websense Endpoint Clients 3.

There are a few ways to distribute the endpoint software: Manually on each endpoint device See Deploying endpoint clients manually, page 437. Using System Center Configuration Manager (SCCM) or Systems Management Server (SMS) (Windows only) See Creating and distributing Websense endpoints using SCCM or SMS for details. 436 Choosing and Deployment Data Security Agents Installing and Deploying Websense Endpoint Clients Using a Microsoft Group Policy Object (GPO) or other third-party deployment tool for Windows. The GPO command for deploying Web Endpoint is displayed on the Settings > Hybrid Configuration > Hybrid User Identification page in TRITON - Web Security. Note that the command includes a WSCONTEXT parameter that is required to ensure that your organization’s policies are applied to user requests. See Manually deploying Web Endpoint for Windows in the TRITON - Web Security Help for details. Instructions for deploying Remote Filtering Client via GPO can be found under Installing with a third-party deployment tool in the Remote Filtering Software technical paper. If you need assistance deploying the Data Endpoint installation package (or any installation package that includes both Data Endpoint and a Web Security endpoint client) via GPO, contact Websense Technical Support. Using Remote Desktop (Mac OS X only) See Installing Mac endpoints with Remote Desktop for details. You can also enable Web Endpoint and Data Endpoint automatic updates to ensure that endpoint client software is kept current after the initial deployment. See: Enabling automatic updates for Data Endpoint, page 438 Enabling automatic updates for Web Endpoint, page 439 To confirm that Web Endpoint or Data Endpoint is installed and running on a machine: For Web Endpoint, go to Start > Control Panel > Administrative Tools > Services. Check that Websense SaaS Service is present in the Services list, and is started. When the Data Endpoint is installed in interactive mode, an icon ( ) appears on the endpoint machine’s task bar. Click the icon for status information. (No icon shows in stealth mode.) For information on endpoint software system requirements, see Endpoint solution system requirements, page 423. If you plan to deploy multiple endpoint solutions (data and Web) on the same machine, see Multiple agent limitations, page 441, before proceeding. Deploying endpoint clients manually Windows Windows packages contain a single executable file: WebesenseEndpoint_32bit.exe or WebesenseEndpoint_64bit.exe. First copy this self-extracting executable file to the client machine, then: Deployment and Installation Center 437 Installing and Deploying Websense Endpoint Clients If the package contains only Data Endpoint, only Remote Filtering Client, or a both Data Endpoint and Remote Filtering Client, double-click it to install the endpoint client. If the package contains Data Endpoint and Web Endpoint, the WSCONTEXT argument (used to identify your organization to the hybrid service) must be included in the command string, as follows: WebsenseEndpoint_64bit.exe /v"WSCONTEXT=<token>" Here, <token> is the WSCONTEXT value displayed in the GPO command string on the Settings > Hybrid Configuration > Hybrid User Identification page in TRITON - Web Security. All arguments passed via the /v parameter must be enclosed in straight quotes, as shown in the example. If you are upgrading an existing endpoint client on the Windows machine, and the old client has an anti-tampering password, you must provide the old password when you run the new installation package. For example: WebsenseEndpoint_32bit.exe /v"XPSWD=<password>" Here, “<password>” is the anti-tampering password used by the previous-version endpoint client. All arguments passed via the /v parameter must be enclosed in straight quotes, as shown in the example. Note that if you are upgrading Web Endpoint and Data Endpoint together, you must provide both the XPSWD and WSCONTEXT arguments. For example: WebsenseEndpoint_64bit.exe /v"XPSWD=<password> WSCONTEXT=<token>" Linux Linux packages (Data Endpoint only) contain 2 installers with the same functionality: LinuxEndpoint_SFX_installer_el4 - use with Red Hat Enterprise Linux version 4.x. LinuxEndpoint_SFX_installer_el5 - use with Red Hat Enterprise Linux version 5.x. To install Data Endpoint software on a Linux computer, copy the correct installer to the machine and run it as root. No reboot is necessary. The endpoint software starts automatically. Enabling automatic updates for Data Endpoint To deploy Data Endpoint updates automatically, you must create an update server that hosts endpoint installation packages. See “Automatic Updates for Websense data endpoints” for details. You must also select Receive automatic updates for data endpoints on the Websense Endpoint Package Builder “Server Connections” screen. On this same screen, specify the URL of the server you created and indicate how often you want endpoint machines to check for updates (every 2 hours by default). 438 Choosing and Deployment Data Security Agents Installing and Deploying Websense Endpoint Clients When configured properly, your update server pushes software updates out to endpoint machines and installs the packages in the background silently. Note If you want to change the components installed on a data endpoint with components of the same version (for example, switch from a data and web endpoint combination to a data only endpoint), you must use the package builder to generate a new package and use one of the other deployment options to deploy it. You cannot use the auto-update feature to update endpoints with the same version. Enabling automatic updates for Web Endpoint Once you have deployed your endpoint package to end users, Web Endpoint can be updated for some or all of your hybrid filtering users directly from the hybrid service. If you use the Data Endpoint auto-update feature for endpoints with both data and Web capabilities, however, endpoints receive updates from your auto-update server instead. To enable automatic Web Endpoint updates to client machines: 1. Go to the Settings > Hybrid Configuration > Hybrid User Identification page in TRITON - Web Security. 2. Mark Enable installation and update of Web Endpoint on client machines. This defines whether automatic updates are deployed to the client machines that you specify. If you uncheck this option at a later date, no further automatic updates occur. However, the installed endpoint software continues to run until it is uninstalled from the client machines. 3. Mark Automatically update endpoint installations when a new version is released. 4. Click OK to cache your changes. Changes are not implemented until you click Save All. Note At the completion of any endpoint update, you must restart the endpoint for the updates to take effect. Note that while a Web Endpoint update is taking place (which can take several minutes), end users are unable to browse, but are shown a Web page explaining that the update is occurring. This page continues to retry the requested Web page every 10 seconds until the endpoint software has finished updating. The request is then submitted, and either the page or a block page is displayed.

If you used an SMS distribution system to create packages for installation, those packages can be reused, with a slight modification, for uninstalling the software. If a package was not created for deployment of the endpoint software, a new one needs to be created for uninstalling. To uninstall with package: 1. Follow the procedure for Creating and distributing Websense endpoints using SDCCM or SMS. 2. In step 1, select Per-system uninstall. 3. Complete the remaining procedures. 4. After deploying the package, the Websense Endpoint will be uninstalled from the defined list of computers. Multiple agent limitations Deployment and Installation Center | Web and Data Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.7.x In this topic Multiple Websense endpoints, page 442 Third-party agents, page 442 Data Security, v7.7.x Some Websense endpoint clients can run together on the same machine. For example, Data Endpoint can be installed with Web Endpoint or Remote Filtering Client. Deployment and Installation Center 441 Installing and Deploying Websense Endpoint Clients Endpoint software can also be installed with third-party agents, such as an antivirus agent. There are limitations in all multi-agent deployments to be aware of. Multiple Websense endpoints With the Websense Endpoint Package Builder, you can create packages for multiple agents (Web and data) and, depending on the agent, multiple operating systems (Windows and Linux). You can deploy these packages to the same or different endpoint (client) machines. For example, you can deploy either Web Endpoint and Data Endpoint or Remote Filtering Client and Data Endpoint on the same machine. You cannot deploy Web Endpoint and Remote Filtering Client on the same machine. The package builder does not let you create a single package containing both. Likewise, you cannot deploy multiple agents on Linux machines. Only Data Endpoint supports Linux. Here are some other restrictions to consider: If you are deploying Web and data endpoints on the same machine, you must deploy them at the same time. The packages created by the Websense Endpoint Package Builder are backwards compatible with previous endpoint versions. Third-party agents By default, Windows XP and Windows Server 2003 limit the number of concurrent agents in a system. As a result, a fatal (BSOD) error may occur when users try to access files via DFS (Distributed File System) and Websense endpoint software is installed with more than 2 other agents. To overcome this limitation, update client operating systems to Windows XP SP3 or Windows Server 2003 SP2 and follow the procedures below. For further details, please refer to: http://support.microsoft.com/kb/906866. On all relevant endpoint (client) machines: 1. Make a backup copy of your Windows registry before you continue. See support.microsoft.com for details. 2. Click Start > Run and type regedit, then click OK. 3. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Mup\ Parameters 442 Choosing and Deployment Data Security Agents Installing and Deploying Websense Endpoint Clients 4.

Network Agent will not function correctly if installed on the Check Point machine. Warning Do not install Network Agent on the same machine as Check Point software. Getting started with a Check Point integration Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Distributed environments, page 451 Client computers and Check Point products, page 451 Communicating with Websense software, page 451 Installing Web Filter or Web Security to integrate with Check Point, page 452 Upgrading Web Filter or Web Security when integrated with Check Point, page 453 Migrating between Check Point versions, page 453 Websense Web Filter and Web Security are compatible with the following Check Point products: Check Point NGX and NGX 65 Check Point UTM-1 (VPN-1) Edge Websense Web Filter or Web Security integration with Check Point works as follows: Websense Filtering Service interacts with the Check Point product and Network Agent to filter Internet requests. Deployment and Installation Center 449 Integrating Web Security with Check Point Websense Network Agent manages Internet protocols that are not managed by the Check Point product. Important Do not install Network Agent on the Check Point machine. Check Point products provide network security and a framework for content filtering. Websense software communicates with the Check Point product via URL Filtering Protocol (UFP). Websense software is implemented as a UFP Server, and communicates with the Check Point product over TCP sockets. By default, Websense software listens on port 18182 for messages from the Check Point product. To begin filtering: Client computers must point to the machine running the Check Point product as their default gateway. Typical networks implement this configuration for security reasons unrelated to filtering. The Check Point product must be configured to use a rule to analyze all HTTP requests, as well as FTP requests issued by a browser that proxies to the Check Point product. The rule must use the URI Specifications for HTTP. Note If Websense software must download the Master Database through a proxy server or firewall that requires authentication for any HTTP traffic, the proxy server or firewall must be configured to accept clear text or basic authentication. When Websense software is integrated with a Check Point product, you define policies within TRITON - Web Security (the configuration interface for Websense software). These policies identify which of the Websense categories are blocked or permitted during different times and days. Within the Check Point product, you typically define a rule that directs the firewall to reject requests for sites in Websense categories whose action is set to block, limit by quota, or confirm. If a client selects an option to view a site with quota time on a block page, Websense software tells the Check Point product to permit the site. When the Check Point product receives an Internet request for either an HTTP site or an FTP site requested by a browser that uses the firewall as a proxy, it queries Websense Filtering Service to determine if the site should be blocked or permitted. Filtering Service checks the policy assigned to the client. Each policy designates specific time periods and lists the category filters that are in effect during those periods. After Filtering Service determines which categories are blocked for that client, it checks the Websense Master Database to locate the category for the requested URL: 450 Websense Web Security and Web Filter Integrating Web Security with Check Point If the site is assigned to a blocked category, the client receives a block page instead of the requested site. If the site is assigned to a permitted category, Filtering Service notifies the Check Point product that the site is not blocked, and the client is allowed to see the site. Distributed environments When the SmartCenter™ server is separated from the Enforcement Module, modify your Rule Base to allow the SmartCenter Server to communicate with Websense Filtering Service during setup. This allows the Check Point product to load the Websense dictionary, which contains the categories Blocked and Not Blocked. All other communication is between Filtering Service and the Enforcement Module. See Check Point documentation for instructions on modifying the Rule Base. Client computers and Check Point products Check Point products process HTTP requests transparently, so no Internet browser changes are required on client computers. You can have clients proxy to the firewall to enable user authentication within that firewall, or to enable filtering of FTP requests from a browser. See Check Point product documentation for instructions on handling FTP requests. If clients use the firewall as a proxy, browsers on client computers must be configured to support proxy-based connections. Communicating with Websense software Depending on which Check Point product is running, Websense software may communicate with the firewall through a secure connection or a clear connection. A secure connection requires that communication between the Check Point product and the Websense UFP Server is authenticated before any data is exchanged. A clear connection allows Websense software and the Check Point product to transfer data without restrictions. The connection options for each supported Check Point product version are similar, but have some slight differences. FireWall-1 NGX or FireWall-1 NG with Application Intelligence (AI): clear connection is the default. An authenticated connection can be established, but is not recommended because of performance issues. In addition, a clear connection is required to use the Enhanced UFP Performance feature described in the next section. FireWall-1 NG Feature Pack 1 or later: clear connection is the default, but a Secure Internal Communication (SIC) trust connection can be configured within both Check Point and Websense software. Deployment and Installation Center 451 Integrating Web Security with Check Point See Configuring Check Point products to work with Web Security solutions, page 454, for the appropriate procedures to establish secure or clear communication with the Websense software. Enhanced UFP performance The enhanced UFP performance feature increases the amount of traffic that Websense software and the Check Point product can filter while reducing CPU load. Configuring enhanced UFP performance requires the proper settings in both Websense software and the Check Point product. See Configuring enhanced UFP performance, page 464, for detailed configuration procedures. Note To use enhanced UFP performance, Websense software and the Check Point product must be configured for clear communication. Installing Web Filter or Web Security to integrate with Check Point Refer to Installing Web Security components, page 392, for complete installation instructions. When installing Filtering Service, follow the installation instructions until prompted to select an integration option. On the Integration Option screen, select Integrated with another application or device. On the Select Integration screen, select Check Point. If Network Agent is included in this installation, a warning advises against installing Network Agent on the same machine as the firewall. An exception allows Websense software and the firewall to be installed on an appliance with separate virtual processors to accommodate both products. Select Yes, install Network Agent only if the machine has separate virtual processors. Follow the remaining screens in the Websense installer to complete the installation. See Configuring Check Point products to work with Web Security solutions, page 454, for information on configuring the firewall integration with Websense software. If Filtering Service is installed on a multihomed machine, identify Filtering Service by its IP address in your network so that Websense block messages can be sent to users. See Identifying Filtering Service by IP address, page 679, for instructions. 452 Websense Web Security and Web Filter Integrating Web Security with Check Point Upgrading Web Filter or Web Security when integrated with Check Point Before upgrading Websense software, make sure your Check Point product is supported by the new version. Follow the instructions in Upgrading Websense Web Security Solutions, page 579. Update the Check Point dictionary with new Websense settings, and update the Websense Resource Object in SmartCenter before you begin filtering with the new version of Websense software. For more information, see Configuring Check Point products to work with Web Security solutions, page 454. Migrating between Check Point versions If you plan to upgrade your Check Point product (from FireWall-1 NG to NGX, for example), do so after upgrading the Websense software. Important Do not make any additional modifications to your Websense software until after you have upgraded your firewall product. See Upgrading Websense Web Security Solutions, page 579, for instructions on upgrading Websense software. See Check Point documentation for information on upgrading the Check Point software. See Configuring Check Point products to work with Web Security solutions, page 454, for the necessary configuration procedures to ensure that your new version of the Check Point product can communicate with Websense software. Deployment and Installation Center 453 Integrating Web Security with Check Point Configuring Check Point products to work with Web Security solutions Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Creating a network object, page 455 Creating an OPSEC application object, page 456 Creating Resource Objects, page 458 Defining rules, page 461 Configuring enhanced UFP performance, page 464 In addition to defining Websense policies and assigning them to the appropriate clients, you must set up the Check Point product with the necessary objects and rules. In describing these objects and rules, this chapter assumes that you are familiar with general Check Point product concepts. The following tasks must be completed before you begin to configure the Check Point product to communicate with Websense software: Both the Check Point product and Websense Web Filter or Web Security must be installed and running. In the Check Point product, create: An object for the firewall itself, if it does not already exist (it typically is created by default upon installation of the Check Point product). Objects that represent your network topology (as needed for filtering). See Check Point product documentation for more information on objects. Configuring NGX for Websense content filtering involves the following procedures: Create a network object for the machine running Websense Filtering Service. See Creating a network object, page 455. Create an OPSEC™ application object for the Websense UFP Server. See Creating an OPSEC application object, page 456. Create URI resource objects for the dictionary categories that Websense software sends to the Check Point product. See Creating Resource Objects, page 458. When creating the URI resource objects, you can configure both Websense software and the Check Point product to use Secure Internal Communication (SIC), rather than the default clear communication. See Establishing Secure Internal Communication, page 468. 454 Websense Web Security and Web Filter Integrating Web Security with Check Point To return to clear communication, see Restoring Clear Communication, page 475. Define rules that govern how the Check Point product behaves when it receives a response from Websense software. See Defining rules, page 461. Optionally, you can configure the Check Point product for enhanced UFP performance. Make sure that you have configured the Check Point product for Websense content filtering before this procedure. See Configuring enhanced UFP performance, page 464. Creating a network object 1. Open a Check Point SmartConsole, such as SmartDashboard™ (Policy Editor in earlier versions). See your Check Point product documentation for detailed instructions on using SmartConsole. 2.

Select Policy > Install to install the policy on the firewall. See Check Point product documentation for more information. 460 Websense Web Security and Web Filter Integrating Web Security with Check Point Defining rules This section describes a content filtering scenario and its configuration. It includes information about the objects and rules that are needed to implement the suggested configuration. Note The configuration described in this section assumes that all clients have a default route set to the firewall and do not proxy to the firewall. This configuration also assumes that the recommended network configuration is being used: Websense software is running on a separate machine, behind the firewall, and caching is disabled. In this scenario, the Check Point product denies access to any site that Websense software indicates is blocked, and allows access to any site that Websense software indicates is not blocked. The actual sites blocked may vary according to the computer making the request. Use TRITON - Web Security to define policies that block the appropriate categories, and assign them to the desired computers or directory objects. For example, you might modify the Default policy to use a category filter that blocks access to all categories except the Travel, and Business and Economy categories. This policy is applied to most computers. A separate, more liberal policy could be defined for managers, which blocks only those categories considered a liability risk, such as Adult Material and Gambling. This policy, called Management, would be assigned to the computers used by top managers. After the Websense policies are configured, you define rules in the Check Point product to prevent access to any site that Websense software indicates is blocked. To set up this configuration in the Check Point product, you must create one URI Resource Object and one Network Object, and define two rules. Create a URI Resource Object for the Blocked category as described in Creating Resource Objects, page 458. In this example, the URI Resource Object is called Blocked_Sites because Websense software is configured to block sites that are not required for business purposes. Create a Network Object that encompasses all machines on the internal network. This example assumes that everyone in the company is on the internal network. For this example, the Network Object is called Internal_Network. Add the rules to the Security Rules Base. The sequence of the rules is important, because the Check Point product evaluates the rules sequentially, from top to bottom. Deployment and Installation Center 461 Integrating Web Security with Check Point RULE 1: Blocks access to undesirable Web sites. Add the new rule at an appropriate location in the Rule Base: Name (NGX only) Enter a descriptive name for the rule, such as Websense Block. Source Add Internal_Network Destination Any (default) Service Add with Resource In the Service with Resource dialog box, select HTTP. Under Resource, select Blocked_Sites from the drop-down menu. This object was created in Creating Resource Objects, page 458. Action Reject Track None Install On Policy Targets Time Any (default) Comment (NGX only) Enter a more detailed description of the rule. RULE 2: The second rule allows access to all other Web sites. Add the second rule after Rule 1. Name (NGX only) Enter a descriptive name for the rule, such as Websense Allow Source Add Internal_Network Destination Any (default) Service Add/HTTP Action Accept Track None Install On Policy Targets Time Any (default) Comment (NGX only) Enter a more detailed description of the rule. 462 Websense Web Security and Web Filter Integrating Web Security with Check Point The following illustrations provide examples of Security Rule Base after the rules are defined. After defining the rules described above, Verify and Install the policy from the Policy menu. See Check Point product documentation for more information. Important For normal operation, set Track to None in the Websense rules. This disables logging in the Check Point product. When logging is enabled for these rules, the log files become very large, and adversely impact performance. Configure other options in the Track field only when you are testing and troubleshooting. When the Check Point product receives an HTTP request, it sends Websense software the address of the requested site, as well as the IP address of the computer requesting the site. For example, the CNN Web site is requested by a top manager. Websense software categorizes the site as News and Media. Websense software indicates that the site is Not Blocked under the Management policy that you defined in TRITON - Web Security. The Check Point product allows the site according to Rule 2. If the CNN site was requested from an accounting clerk’s computer, Websense software indicates that the site is Blocked because that computer is governed by the Websense Default policy, which blocks the News and Media category. The Check Point product denies the request according to Rule 1, and a Block Page is displayed on the clerk’s computer. Any time a computer requests a site not categorized by the Websense Master Database, Websense software indicates that the site is not in the database. The Check Point product allows access to the site according to Rule 2. Deployment and Installation Center 463 Integrating Web Security with Check Point Configuring enhanced UFP performance Enhanced UFP performance improves the performance of the UFP Server by increasing the amount of traffic that Websense software and the Check Point product can filter while reducing CPU load. Configuring enhanced UFP performance requires the proper settings in Websense Web Security or Websense Web Filter, and in the Check Point product. In order to use enhanced UFP Performance, clear communication is required between Websense software and the Check Point product. Note Before performing the following procedures, make sure you have configured the Check Point product for content filtering with Websense software, as described earlier in this chapter. Websense configuration Before configuring the Check Point product for enhanced UFP performance, open the ufp.conf file and make sure Websense software is configured for clear communication: 1. On the Websense Filtering Service machine, navigate to the directory where the Check Point integration files are installed. The default directories are: Windows: C:\Program Files or Program Files (x86)\Websense\Web Security\bin Linux: /opt/Websense/bin 2. Open the ufp.conf file in any text editor. The file must contain the following line to be configured for clear communication: ufp_server port 18182 Additional lines that appear in this file are used for Secure Internal Communication, and must be commented out using the comment symbol (#): #ufp_server auth_port 18182 #opsec_sic_policy_file ufp_sic.conf #opsec_sic_name "place_holder_for_opsec_SIC_name" #opsec_sslca_file opsec.p12 3. Edit the file, if necessary, to match the commands in the previous step. 4. Save and close the ufp.conf file. 5. Stop and restart the Websense UFP Server: Windows: Use the Windows Services dialog box.

Deployment and Installation Center 467 Integrating Web Security with Check Point Configuring CheckPoint secure communication Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: In this topic Web Filter and Web Security, v7.7.x Establishing Secure Internal Communication, page 468 Restoring Clear Communication, page 475 ISecure Internal Communication (SIC) may be needed when you integrate a Check Point product with Websense software. Following are instructions for enabling and disabling this communication method. Establishing Secure Internal Communication If Websense software is integrated with a FireWall-1 NG version, you can configure both programs to use Secure Internal Communication (SIC). A secure connection requires that communication between the Check Point product and the Websense UFP Server be authenticated before any data is exchanged. Note The use of SIC with Websense software creates performance problems and is not recommended for networks with more than 100 users. After installing Filtering Service, establish an SIC trust between the Check Point product and Websense software: Configure the OPSEC Application object for the Websense UFP Server within the Check Point product to use Secure Internal Communication. See Configuring the Check Point product to use SIC, page 469. Configure Websense software to use Secure Internal Communication. See Configuring Websense software to use SIC, page 471. Update the OPSEC Application object within the Check Point product to receive secure communications from Websense software. See Updating the OPSEC Application object, page 473. Prerequisites The following must be completed before you begin to configure the Check Point product to communicate with Websense software, as described in Chapter 2 of this Supplement. 468 Websense Web Security and Web Filter Integrating Web Security with Check Point Both the Check Point product and Websense software must already be installed and running. In the Check Point product, create the following objects: An object for the firewall. Consult Check Point product documentation for instructions. Network Objects that represent your network topology (as needed for your filtering goals) must exist. Consult Check Point product documentation for instructions. You must create the OPSEC Application object for the Websense UFP Server before Websense software can establish SIC. If you have not already done this, see the procedures in Creating an OPSEC application object, page 456. Note Do not perform the procedures in this section if you are using an earlier version of FireWall-1 (before FireWall-1 NG Feature Pack 1). Configuring the Check Point product to use SIC 1. Open the SmartDashboard, and select Manage > Servers and OPSEC Applications. 2. Double-click the OPSEC Application object you created for the Websense UFP Server in Creating an OPSEC application object, page 456. The OPSEC Application Properties dialog box for this object appears. Deployment and Installation Center 469 Integrating Web Security with Check Point 3. If clear communication (for early version compatibility mode) is enabled, disable it: a. Go to the UFP Options tab of the OPSEC Application Properties dialog box for this object. b. Make sure the Use early versions compatibility mode check box is not selected. (This field was called Use backwards compatibility mode in earlier versions.) 4. Click Communication. The Communication dialog box appears. 470 Websense Web Security and Web Filter Integrating Web Security with Check Point 5. Enter and confirm an Activation Key (password) for communication between Websense Filtering Service and the Check Point product. (Make a note of this password for later use.) 6. Click Initialize. The Trust state field must show Initialized but trust not established. 7. Click Close to return to the OPSEC Application Properties dialog box, then click OK. 8. Close the Servers and OPSEC Applications dialog box. 9. Select Policy > Install to install the policy on the firewall. See the Check Point product documentation for more information. Configuring Websense software to use SIC Use this procedure to obtain a SIC certificate from the Check Point product, and configure Websense software to use it. After you complete this procedure, Websense software sends this certificate each time it communicates with the Check Point product. 1. Open a command prompt on the Websense Filtering Service machine and navigate to the directory containing the Check Point integration files (C:\Program Files or Program Files (x86)\Websense\Web Security\bin or /opt/Websense/bin, by default). 2. Enter the following command: opsec_pull_cert –h <host> -n <object> -p <password> -o <path> The table below explains the variables for this command. Variable Description <host> The IP address or machine name of the computer on which the SmartCenter Server (Management Server in earlier versions) is installed. This IP address may be the same machine as the Enforcement (FireWall) Module or a different machine. <object> The name of the OPSEC Application object created for the Websense UFP Server. <password> The activation key that you entered for the named OPSEC Application object. See Configuring the Check Point product to use SIC, page 469. <path> Path to the output certificate file, opsec.p12. This variable must be expressed as a complete path. If the OPSECDIR variable already exists, the default path is $OPSECDIR/opsec.p12. If the OPSECDIR variable does not exist, the opsec.p12 file is created in the same folder as the opsec_pull_cert.exe file (Websense\bin or Websense/bin/FW1). Deployment and Installation Center 471 Integrating Web Security with Check Point This command contacts the firewall and downloads the Secure Internal Communication certificate that authorizes Websense software to communicate with the Check Point product, and saves the certificate in a file, opsec.p12. The command line displays information similar to the following example: opsec_pull_cert –h 10.201.254.245 –n Websense_UFP –p firewall –o "C:\Program Files\Websense\bin\opsec.p12" The full entity sic name is: CN=Websense_UFP,0=fw1_server..dwz26v Certificate was created successfully and written to "opsec.p12". 3. Write down the SIC name displayed by the opsec_pull_cert command. In the example above, the SIC name is: CN=Websense_UFP,0=fw1_server..dwz26v 4. Open the ufp.conf file, located by default in the C:\Program Files or Program Files (x86)\Websense\Web Security\bin or /opt/Websense/bin directory. The default file contains the following syntax: ufp_server port 18182 #ufp_server auth_port 18182 #opsec_sic_policy_file ufp_sic.conf #opsec_sic_name "place_holder_for_opsec_SIC_name" #opsec_sslca_file opsec.p12 The first line is used for clear communication. The remaining lines are used for SIC. If the file does not contain the lines for SIC shown above, enter them. 5. To enable secure communication, comment out the first line and remove the comment symbol (#) from the remaining four lines. #ufp_server port 18182 ufp_server auth_port 18182 opsec_sic_policy_file ufp_sic.conf opsec_sic_name "place_holder_for_opsec_SIC_name" opsec_sslca_file opsec.p12 6. On the opsec_sic_name line, replace the placeholder with the SIC name recorded in Step 3. The name must be enclosed in quotation marks. For example: opsec_sic_name "CN=Websense_UFP,0=fw1_server..dwz26v" The completed file: #ufp_server port 18182 ufp_server auth_port 18182 opsec_sic_policy_file ufp_sic.conf opsec_sic_name "CN=Websense_UFP,0=fw1_server..dwz26v" opsec_sslca_file opsec.p12 7. Save and close the file. 472 Websense Web Security and Web Filter Integrating Web Security with Check Point 8. Stop and restart the Websense UFP Server: Windows: Use the Windows Services dialog box. Linux: Use the ./WebsenseAdmin restart command. See Starting and stopping Web Security services, page 709, for instructions on stopping and restarting Websense services. See also Stopping and restarting the UFP Server, page 473. Stopping and restarting the UFP Server Filtering Service must be running for the Websense UFP Server to function. When the Filtering Service is stopped, the UFP Server is automatically shut down. The UFP Server must be restarted manually. If the UFP Server is started first, it automatically starts the Filtering Service. Stopping or starting the UFP Server while the Filtering Service is running has no effect on the Filtering Service.

Websense software creates Websense.log and ufpserver.log files when errors occur. These files are located in the Websense bin directory, (C:\Program Files or Program Files (x86)\Websense\Web Security\bin or /opt/Websense/bin, by default.) These log files record error messages and other messages pertaining to database downloads. Websense.log is located only on the machine running Policy Server. The Master Database does not download In addition to the subscription and access problems discussed in the Websense , a rule in the firewall could be blocking the download. Create a rule in the Check Point product at the top of the rule base that allows all traffic (outbound) from the Websense Filtering Service machine. If this test succeeds, move the rule down systematically until the problematic rule is found. Websense dictionary does not load in the Check Point product The Get Dictionary process occurs between the Check Point SmartCenter Server and Websense Filtering Service. If the SmartCenter Server is not installed on the same machine as the Check Point Enforcement Module, you may need to configure the Check Point product to allow communication between the machines running the SmartCenter Server and Filtering Service. See Distributed environments, page 451, for more information. Three causes are listed below as to why the dictionary might not load within the Check Point product. Deployment and Installation Center 477 Integrating Web Security with Check Point Port mismatch If the FW1_ufp Service defined in the Check Point product uses a different port than Filtering Service filtering port (default 18182), Websense software cannot communicate with the Check Point product. As a result, the Check Point product cannot retrieve the Websense dictionary entries. Check for mismatched port entries in the following locations: Check the FW1_ufp Service definition in the Check Point product. 1. From the Check Point client, select Manage > Services. 2. Select FW1_ufp from the list of services, then click Edit. The TCP Services Properties dialog box appears. 3. Make sure the port number displayed is the same as the port number defined for the filtering port when you installed Filtering Service. Open the ufp.conf file in a text editor. The file is located by default in the C:\Program Files or Program Files (x86)\Websense\Web Security\bin\FW1 or / opt/Websense/bin/FW1 directory. Check the port value to make sure it matches the port setting for the FW1_ufp Service in the Check Point product. In the Check Point product, the filtering port specified in the fwopsec.conf file must match the port number set for the FW1_ufp Service and the port defined in the Websense ufp.conf file. Note If the SmartCenter Server and the Enforcement Module are installed on separate machines, both contain an fwopsec.conf file. You must reconcile the filtering port number in each of these files. Communication mismatch If the Websense dictionary does not load, check your communication settings. The method of communication selected in the OPSEC Application object must be consistent with that defined in the ufp.conf file (SIC or clear communication). For example, if you have selected early version compatibility mode in the OPSEC Application Properties dialog box (see Early versions compatibility mode, page 465), the first line in the ufp.conf file must be: ufp_server port 18182 If you have selected SIC, the first line in the ufp.conf file must be: ufp_server auth_port 18182 Policy properties Although it is enabled by default, some environments need to disable the Accept Outgoing Packet Originating from Gateway setting in the Check Point product’s 478 Websense Web Security and Web Filter Integrating Web Security with Check Point policy properties. Since the firewall cannot send any traffic in this environment, it cannot request the dictionary. To enable the dictionary request, add the following rule to the Rule Base anywhere before the cleanup rule: Source Check Point product workstation object Destination Any, or the Filtering Service workstation object Service FW1_ufp Action Accept Track Long (or any desired setting) Install On SRC (Required) Time Any FTP requests are not being blocked as expected Websense software cannot block FTP requests when the Check Point product is configured to act as a proxy server. The FTP request is sent as ftp://. The Check Point product then sends the packet to the Websense software with an http:// header. Websense software performs a lookup against HTTP categories instead of performing a protocol lookup, and the FTP request is blocked or permitted according to the category assigned to the HTTP version of the same URL. It is recommended that you use the capability of the Check Point product to block the FTP protocol. 1. In the Check Point product, create a rule that blocks on the FTP service. See Check Point product documentation for more information. 2. Place this rule above the Websense rule. 3. Save the policy. Users receive the Check Point block page instead of the Websense block page. Note In this case, it is not necessary to set the FTP protocol to be blocked in TRITON - Web Security. Deployment and Installation Center 479 Integrating Web Security with Check Point 480 Websense Web Security and Web Filter 20 Integrating Web Security with Cisco Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Websense Web Filter and Web Security can be integrated with Cisco® Adaptive Security Appliance (ASA), Cisco PIX® Firewall, Cisco IOS routers, and Cisco Content Engine. See System requirements for this version, page 2, for a list of Cisco products supported for integration with Websense Web Filter or Web Security. Integrating with a Cisco product involves the following components: Websense Filtering Service works with the Cisco product and Network Agent to respond to Internet requests. For redundancy, two or more instances of Filtering Service may be used. Only one instance (the primary server) is active at any given time. URL look-up requests are be sent only to the primary server. Websense Network Agent manages Internet protocols that are not managed by your integrated Cisco product. Network Agent can also provide information for reports on bandwidth and block Internet requests based on bandwidth consumption. If Network Agent is installed, you must define the IP addresses of all proxy servers through which computers route their Internet requests. See Network Configuration in the TRITON - Web Security Help for instructions. If HTTP(S) or FTP authentication is enabled in the Cisco product, Websense User Service must be installed in the same domain or root context as authenticated users to get correct user information and provide it to Filtering Service for accurate user-based filtering. If you are using a Websense transparent identification agent or manual authentication, this configuration is not necessary. To enable the integration, direct Internet requests through your Cisco product, and configure it for use with Websense software.

Deployment and Installation Center 485 Integrating Web Security with Cisco Getting started with a Cisco integration Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic How Websense filtering works with Cisco products, page 486 Installation of Web Filter or Web Security, page 487 Upgrading Websense Web Filter or Web Security, page 487 Migrating between integrations after installation, page 488 Network Agent enhanced logging, page 489 Related topics: Deployment considerations for integration with Cisco products, page 482 Configuring a Cisco Security Appliance, page 489 Configuring a Cisco IOS Router, page 500 Configuring a Cisco Content Engine, page 507 How Websense filtering works with Cisco products To be filtered by Websense software, a client's Internet requests must pass through the Cisco product. If Websense software is integrated with a Cisco PIX Firewall or ASA, browser requests must go through the PIX Firewall or ASA to reach the Internet. If Websense software is integrated with a Cisco Content Engine, client browser requests may be forwarded to the Content Engine transparently or explicitly. See Cisco Content Engine and browser access to the Internet, page 512. When it receives an Internet request, the Cisco product queries Filtering Service to determine if the requested Web site should be blocked or permitted. Filtering Service consults the policy assigned to the user. Each policy designates specific time periods and lists the category filters that are applied during those periods. After Filtering Service determines which categories are blocked for that client, it checks the Websense Master Database. For HTTP, if the site is assigned to a blocked category, the user receives a block page instead of the requested site. 486 Websense Web Security and Web Filter Integrating Web Security with Cisco For HTTPS or FTP, if the site is assigned to a blocked category, the user is not allowed access and receives a blank page. If the site is assigned to a permitted category, Filtering Service notifies the Cisco product that the site is not blocked, and the client is allowed to visit the site. Note Before enabling Websense URL filtering, make sure there is not another URL filtering scheme configured, such as N2H2. There can be only one active URL filtering scheme at a time. Installation of Web Filter or Web Security Install Web Filter or Web Security as directed in Installation overview: Web Filter and Web Security, page 193. When installing Filtering Service, be sure to do the following. On the Integration Option screen, select Integrated with another application or device. On the Select Integration screen, select one of the following and then click Next: Cisco Adaptive Security Appliances Cisco Content Engine Cisco PIX Firewall Cisco Routers Do not install a transparent identification agent if you plan to configure user authentication through your Cisco product. In a Web Security All installation, the Transparent User Identification screen is used to select a transparent identification agent. Select Do not install a transparent identification agent now if you will authenticate users through your Cisco product. In a custom installation (or when adding components), on the Select Components screen, do not select any of the components under User identification if you will authenticate users through your Cisco product. Upgrading Websense Web Filter or Web Security When you upgrade Websense software that is already integrated with a Cisco product, no additional Cisco configuration is necessary. See Upgrading Websense Web Security Solutions, page 579, for upgrading instructions. If you are upgrading your Websense deployment and changing your Cisco product, see Migrating between integrations after installation, page 488. Deployment and Installation Center 487 Integrating Web Security with Cisco Migrating between integrations after installation You can change the Cisco integration product (for example, change from a PIX Firewall to an IOS router) after installing Websense software without losing configuration data. 1. Install and configure your new Cisco integration product. See Cisco documentation for instructions. Ensure that it is deployed so that it can communicate with Filtering Service. 2. Use the Websense Backup Utility to back up the Websense configuration and initialization files. See the TRITON - Web Security Help for instructions. 3. Close all applications on the Filtering Service machine, and stop any antivirus software. 4. Remove Filtering Service. See Removing Web Security components, page 698, for instructions. 5. Restart the machine (Windows only). 6. Use the Websense installer to reinstall Filtering Service. See Installing Web Security components, page 392, for instructions. 7. On the Select Integration screen, select the new Cisco product, and then follow the on-screen instructions to complete the installation. The installer adds the new integration data to the Websense software configuration files, while preserving existing configuration data. 8. Restart the machine (Windows only). 9. Check to be sure that Filtering Service has started. Windows: Use the Windows Services dialog box to verify that Websense Filtering Service has started. Linux: Navigate to the Websense installation directory (/opt/Websense, by default), and use the following command to verify that Websense Filtering Service is running: ./WebsenseAdmin status For instructions on starting Websense services, see Starting and stopping Web Security services, page 709. 10.

Configuring a Cisco Security Appliance Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x After Websense Web Filter or Web Security is installed, the Cisco security appliance, PIX firewall, or Adaptive Security Appliance (ASA) must be configured to work with Websense software. The Cisco firewall passes each Internet request to Filtering Service, which analyzes the request and determines whether to block or permit access, or limit access by using quotas set in Websense policies. See the TRITON - Web Security Help for information about implementing filtering policies. See the following for information about configuring Websense integration with Cisco PIX Firewall or Adaptive Security Appliance (ASA) through a console or Telnet session: Deployment and Installation Center 489 Integrating Web Security with Cisco Cisco configuration command conventions, page 482 Cisco integration configuration procedure, page 490 User-based filtering for Cisco integration, page 498 For information on configuring your security appliance through the management interface, see the documentation for your Cisco product, available at www.cisco.com. Note In this topic, the term security appliance is used to refer to both Cisco PIX Firewall and ASA collectively. Cisco integration configuration procedure Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: In this topic Web Filter and Web Security, v7.7.x Configuration procedure, page 490 Parameters for the filter commands, page 497 Configuration procedure To configure your security appliance to send Internet requests to Websense software for filtering: 1.

Use the url-server command to enable URL filtering by Websense software. 490 Websense Web Security and Web Filter Integrating Web Security with Cisco url-server (<if_name>) vendor websense host <ip_address> [timeout <seconds>] [protocol {TCP | UDP} version {1 | 4} [connections <num_conns>]] The url-server command takes the following parameters: Parameter Definition (<if_name>) The network interface where Websense Filtering Service resides. In v7.0 of the Cisco security appliance software, a value for this parameter must be entered. In v6.3.1 and earlier, <if_name> defaults to inside if not specified. You must type the parentheses ( ) when you enter a value for this parameter. vendor websense Indicates the URL filtering service vendor is Websense. <ip_address> IP address of the machine running Filtering Service. timeout <seconds> The amount of time, in seconds, that the security appliance waits for a response before switching to the next Filtering Service that you defined as a url-server, or, if specified, going into allow mode and permitting all requests. If a timeout interval is not specified, this parameter defaults to 30 seconds in v7.0(1) and later, and 5 seconds in earlier versions of the Cisco PIX or ASA software. v7.0(1) and later: Range: 10 - 120; Default: 30 v6.3: Range: 1 - 30; Default: 5 protocol {TCP | UDP} version {1 | 4} Defines whether the Cisco security appliance should use TCP or UDP protocol to communicate with Filtering Service, and which version of the protocol to use. TCP is the recommended and default setting. The recommended protocol version is 4. The default is 1. (Note: To send authenticated user information to Filtering Service, TCP version 4 must be selected.) connections <num_conns> Limits the maximum number of TCP connections permitted between the Cisco security appliance and Filtering Service. If this parameter is not specified, it defaults to 5, which is the recommended setting. If you select the UDP protocol, this option is not available. Range: 1 - 100; Default: 5. Example: Deployment and Installation Center 491 Integrating Web Security with Cisco url-server (inside) vendor websense host 10.255.40.164 timeout 30 protocol TCP version 4 connections 5 The url-server command communicates the location of Filtering Service to the Cisco security appliance. More than one url-server command can be entered. Multiple commands allow redirection to another Filtering Service after the specified timeout period, if the first server becomes unavailable. 6. Configure the security appliance to filter HTTP requests with the filter url command. To review the current URL server rules, enter show running-config urlserver (v7.0) or show url-server (v6.3). To review all the filter rules, enter show running-config filter (v7.0) or show filter (v6.3). To configure HTTP request filtering, use the following command: filter url http <port>[-<port>] <local_ip> <local_mask> <foreign_ip> <foreign_mask> [allow] [cgi-truncate] [longurl-truncate | longurl-deny] [proxy-block] For an explanation of the filter url parameters, see Parameters for the filter commands, page 497. Examples: Command example Action filter url http 0 0 0 0 Filters every HTTP request to all destinations.

Filtering is applied to traffic on port 443. Using zeroes for the last two entries, <foreign_ip> and <foreign_mask>, allows access from the specified local IP address to all Web sites, as filtered by Websense software. You can enter multiple filter https commands to set up different portions of the network for filtering. Set up the smaller groups first, followed by the larger groups, to assure that all groups are filtered properly. Use a general filter https command for all computers to be filtered, and then use TRITON - Web Security to apply filtering policies to individual clients (computers, networks, users, groups, and domains [OUs]). See the TRITON - Web Security Help for information about implementing filtering policies. Deployment and Installation Center 493 Integrating Web Security with Cisco 8. Configure the Cisco security appliance to filter FTP requests with the filter ftp command. To review the current URL server rules, enter show run url-server (v7.0) or url-server (v6.3.1). To review all the filter rules, enter show run filter (v7.0) or show filter (v6.3.1). If you are running v7.0 of Cisco software, enter exit to go up a level to run the show command. Note The filter ftp command is supported in v6.3.1 and higher of the Cisco PIX Firewall/ASA software. To configure FTP request filtering, use the following command: filter ftp <port> <local_ip> <local_mask> <foreign_ip> <foreign_mask> [allow] [interact-block] For an explanation of the filter ftp parameters, see Parameters for the filter commands, page 497. Examples: Command example Action filter ftp 21 0 0 0 0 Filters every FTP request to all destinations. Filtering is applied to traffic on port 21. filter ftp 21 10.5.0.0 255.255.0.0 0 0 Filters the 10.5.x.x network going to any destination. Filtering is applied to traffic on port 21. filter ftp 21 10.5.0.69 255.255.255.255 132.239.29.189 255.255.255.255 Filters the 10.5.0.69 host going to the 132.239.29.189 destination. Filtering is applied to traffic on port 21. Using zeroes for the last two entries, <foreign_ip> and <foreign_mask>, allows access via Websense software from the specified local IP address to all Web sites. You can enter multiple filter ftp commands to set up different portions of the network for filtering. Set up the smaller groups first, followed by the larger groups, to assure that all groups are filtered properly. Use a general filter ftp command for all computers to be filtered, and then use TRITON - Web Security to apply filtering policies to individual clients (computers, networks, users, groups, and domains [OUs]). See the TRITON - Web Security Help for information about implementing filtering policies. 494 Websense Web Security and Web Filter Integrating Web Security with Cisco 9. After entering commands to define filtering for HTTP, HTTPS, and FTP requests, you can define any required exceptions to these filtering rules by adding the except parameter to the filter command: filter {url | https | ftp} except <local_ip> <local_mask> <foreign_ip> <foreign_mask> This command allows you to bypass Websense filtering for traffic coming from, or going to a specified IP address or addresses. For example, suppose that the following filter command was entered to cause all HTTP requests to be forwarded to Filtering Service: filter url http 0 0 0 0 You could then enter: filter url except 10.1.1.1 255.255.255.255 0 0 This would allow any outbound HTTP traffic from the IP address 10.1.1.1 to go unfiltered. 10. Configure the security appliance to handle long URLs using the url-block urlmempool and url-block url-size commands: Note The url-block commands are supported in v6.2 and higher of the Cisco PIX Firewall/ASA software. a. Increase the size of the security appliance’s internal buffer to handle long URL strings. If the URL buffer size is set too low, some Web pages may not display. To specify the amount of memory assigned to the URL buffer, enter: url-block url-mempool <memory_pool_size> Here, <memory_pool_size> is the size of the buffer in KB. You can enter a value from 2 to 10240. The recommended value is 1500. b. Increase the maximum permitted size of a single URL by adding the following line to the configuration: url-block url-size <long_url_size> Here, <long_url_size> is the maximum URL size in KB. You can enter a value from 2 to 4. The recommended value is 4. 11. Configure the URL response block buffer using the url-block block command to prevent replies from the Web server from being dropped in high-traffic situations. Note The url-block commands are supported in v6.2 and higher of the Cisco PIX Firewall/ASA software. On busy networks, the lookup response from Filtering Service may not reach the security appliance before the response arrives from the Web server. Deployment and Installation Center 495 Integrating Web Security with Cisco The HTTP response buffer in the security appliance must be large enough to store Web server responses while waiting for a filtering decision from the Filtering Service. To configure the block buffer limit, use the following command: url-block block <block_buffer_limit> Here, <block_buffer_limit> is the number of 1550-byte blocks to be buffered. You can enter a value from 1 to 128. To view the current configuration for all 3 url-block commands, enter show running-config url-block (v7.0) or show url-block (v6.3). Enter show url-block block statistics to see how the current buffer configuration is functioning. The statistics include the number of pending packets held and the number dropped. The clear url-block block statistics command clears the statistics. 12. If you need to discontinue filtering, enter the exact parameters in the original filter command, preceded by the word no. For example, if you entered the following to enable filtering: filter url http 10.0.0.0 255.0.0.0 0 0 Enter the following to disable filtering: no filter url http 10.0.0.0 255.0.0.0 0 0 Repeat for each filter command issued, as appropriate. 13. Save your changes in one of the following ways: Either enter the command: copy run start Or enter the commands: exit write memory Websense software is ready to filter Internet requests after the Websense Master Database is downloaded and the software is activated within the Cisco security appliance. See the TRITON - Web Security Help for information about configuring Websense software and downloading the Master Database. 496 Websense Web Security and Web Filter Integrating Web Security with Cisco Parameters for the filter commands The parameters used by the filter http, filter https, and filter ftp commands include the following. Note that some of the parameters listed do not apply to all 3 commands. Parameter Applies to Definition http <port>[-<port>] filter http Defines which port number, or range of port numbers, the security appliance watches for HTTP requests. If you do not specify a port number, port 80 is used by default. The option to set a custom Web port or port range is only available in v5.3 and higher of Cisco software. Note: In Cisco software versions 5.3 to 6.3, it is not mandatory to enter http before the port number; you can either enter http (to use port 80), or you can enter a port number. In Cisco software version 7.0, you must always enter http. <port> filter https filter ftp Defines the port number the security appliance watches for https or ftp requests. The standard HTTPS port is 443. The standard FTP port is 21. <local_ip> filter http filter https filter ftp IP address requesting access. You can set this address to 0.0.0.0 (or in shortened form, 0) to specify all internal clients. This address is the source for all connections to be filtered. <local_mask> filter http filter https filter ftp Network mask of the local_ip address (the IP address requesting access). You can use 0.0.0.0 (or in shortened form, 0) to specify all hosts within the local network. <foreign_ip> filter http filter https filter ftp IP address to which access is requested. You can use 0.0.0.0 (or in shortened form, 0) to specify all external destinations. <foreign_mask> filter http filter https filter ftp Network mask of the foreign_ip address (the IP address to which access is requested). Always specify a mask value. You can use 0.0.0.0 (or in shortened form, 0) to specify all hosts within the external network. Deployment and Installation Center 497 Integrating Web Security with Cisco Parameter Applies to Definition [allow] filter http filter https filter ftp Lets outbound connections pass through the security appliance without filtering when Filtering Service is unavailable. If you omit this option, and Filtering Service becomes unavailable, the security appliance stops all outbound HTTP, HTTPS, or FTP traffic until Filtering Service is available again. [cgi-truncate] filter http Sends CGI scripts to Filtering Service as regular URLs. When a URL hasa parameter list starting with a question mark (?), such as a CGI script, the URL is truncated. All characters after, and including the question mark, are removed before sending the URL to Filtering Service. (Supported in Cisco PIX v6.2 and higher.) [interact-block] filter ftp Prevents users from connecting to the FTP server through an interactive FTP client. An interactive FTP client allows users to change directories without entering the complete directory path, so Filtering Service cannot tell if the user is requesting something that should be blocked. [longurltruncate | longurl-deny] filter http Specify how to handle URLs that are longer than the URL buffer size limit. Enter longurl-truncate to send only the host name or IP address to Filtering Service. Enter longurl-deny to deny the request without sending it to Filtering Service. (Supported in Cisco PIX v6.2 and higher.) [proxy-block] filter http Enter this parameter to prevent users from connecting to an HTTP proxy server. (Supported in Cisco PIX v6.2 and higher.) User-based filtering for Cisco integration Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x 498 Websense Web Security and Web Filter In this topic Overview, page 499 Enable protocol filtering, page 499 Integrating Web Security with Cisco Overview If http, https or ftp authentication is enabled on Cisco Security Appliance, Websense User Service must be installed in the same domain (Windows), or the same root context (LDAP) as authenticated users in order to get correct user information to the Websense Filtering Service component for accurate user-based filtering. Note Cisco Secure ACS can provide user information for one domain only. To transparently identify users in multiple domains, use a Websense transparent identification agent. See the Websense Deployment and Installation Center for information about installing transparent identification agents. If user authentication is not enabled on Cisco Security Appliance, manual authentication or transparent identification agents can be used for user-based filtering. See the TRITON - Web Security Help for information about configuring manual authentication, or configuring transparent identification agents. Enable protocol filtering If user authentication information is provided by Cisco Security Appliance, it can only be used for HTTP(S) and FTP filtering by default. To enable internet protocol filtering, follow these steps: 1. Log on to the machine on which Filtering Service is installed. 2. Stop Filtering Service (See Stopping and starting Websense services in the Installation Guide). 3. Navigate to C:\Program Files\Websense\bin (or, /opt/Websense/bin on Linux). 4. Open eimserver.ini. 5. Add the parameter “CacheWISPUsers=on” in the [WebsenseServer] section. 6. Restart Filtering Service (See Stopping and starting Websense services in the Installation Guide). If user authentication is provided by manual authentication or transparent identification agents, it can be used for both HTTP(S), FTP and internet protocol filtering. Deployment and Installation Center 499 Integrating Web Security with Cisco Configuring a Cisco IOS Router Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x After Websense Web Filter or Web Security is installed, you must configure the Cisco IOS router to send HTTP requests to Websense software. This configuration is done through a console or telnet session. Websense software analyzes each request and tells the router whether or not to permit access or to limit access with quotas, defined in Websense filtering policies. Cisco configuration command conventions, page 482 Cisco IOS startup configuration, page 500 Cisco IOS configuration commands, page 502 Cisco IOS executable commands, page 506 Cisco IOS startup configuration Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Before Websense software can filter Internet requests, the Cisco IOS router must be configured to use Filtering Service as a URL filter. 1. Access the router’s software from a console, or from a remote terminal using telnet. 2. Enter your password. 3. Enter enable and the enable password to put the router into enabled mode. 4. Enter configure terminal to activate configure mode. 5. Enter the following command to identify the Filtering Service machine that will filter HTTP requests: ip urlfilter server vendor websense <ip-address> [port <port-number>] [timeout <seconds>] [retransmit <number>] 500 Websense Web Security and Web Filter Integrating Web Security with Cisco Variable Description <ip-address> The IP address of the machine running Websense Filtering Service. <port-number> The Filtering Service port (also referred to as the integration communication port), default 15868. <seconds> The amount of time the Cisco IOS router waits for a response from Filtering Service. The default timeout is 5 seconds. <number> How many times the Cisco IOS router retransmits an HTTP request when there is no response from Filtering Service. The default is 2. An example of this command is: ip urlfilter server vendor websense 12.203.9.116 timeout 8 retransmit 6 To define an additional Filtering Service instance as a backup, repeat the command using the IP address of the second Filtering Service machine. The configuration settings you create in the following steps are always applied to the primary server. Only one Filtering Service instance is used at a time—referred to as the primary server; all other instances are referred to as secondary. If the primary server becomes unavailable, one of the secondary servers is designated primary. The system goes to the beginning of the list of configured servers (i.e. Filtering Service instances) and attempts to activate the first one. If the first server is not available, the system attempts to activate the next one. This continues until an available server is found or the end of the list of configured servers is reached. If all servers are down, the router goes into allow mode. 6. Enable the logging of system messages to Filtering Service by entering the following command: ip urlfilter urlf-server-log This setting is disabled by default. When logging is enabled, the Cisco IOS router sends a log request immediately after the URL lookup request. 7. Tell the Cisco IOS router how to filter URL requests by entering the following commands, in sequence: ip inspect name <inspection–name> http urlfilter interface <type> <slot/port> ip inspect <inspection-name> {in|out} Examples of these commands are: ip inspect name fw_url http urlfilter interface FastEthernet 0/0 ip inspect fw_url in Deployment and Installation Center 501 Integrating Web Security with Cisco For this sequence to function properly, you must create an inspection rule called fw_url and apply that rule to the inbound interface of the router. See Cisco documentation for information about creating and applying inspection rules. To improve performance, Cisco suggests disabling the Java applet scanner. Java applet scanning increases CPU processing load. To disable the Java applet scanner, use the following commands, in sequence: access-list <num> permit any ip inspect name <inspection–name> http java-list <num> urlfilter See Cisco documentation for more information about these commands. 8. To save your changes: a. Enter the exit command twice to leave the configure mode. b. Enter write memory. These commands store the configuration settings in the Cisco IOS router’s startup configuration so they are not lost if the router is shut down or loses power. 9. Use the following commands to view various aspects of your installations: Command Action show ip inspect name <inspectionname> Displays a specific inspection rule. show ip inspect all Displays all available inspection information. show ip urlfilter config Displays all URL filtering information. <command-name> ? Displays help on individual commands. For example, ip inspect ? displays the complete syntax for the inspect command, and explains each argument. 10. To discontinue filtering or to change a Filtering Service, enter the following command to remove a server configured in Step 5, page 500. no ip urlfilter server vendor websense <ip-address> Cisco IOS configuration commands Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x 502 Websense Web Security and Web Filter Integrating Web Security with Cisco These commands are used to configure the Cisco IOS router to filter HTTP requests through Websense Filtering Service. These configuration settings can be saved into the startup configuration. See Step 8 in the preceding procedure for instructions. Note To turn off a feature or service, add the value no before the command. ip inspect name <inspection-name> http urlfilter [java-list <access-list>] [alert {on|off}] [timeout <seconds>] [audittrail {on|off}] This global command turns on HTTP filtering. The urlfilter value associates URL filtering with HTTP inspection rules. You may configure two or more inspections in a router, but the URL filtering feature only works with those inspections in which the urlfilter field is enabled. This setup command is required. ip port-map http port <num> Use this command to filter proxy traffic on port <num> through Websense Filtering Service. ip urlfilter server vendor websense <IP-address> [port <num>] [timeout <secs>] [retrans <num>] This setup command is required to identify Filtering Service to the Cisco IOS router and configure additional values. When using this command, the Cisco IOS router checks for a primary Filtering Service—one that is active and being sent URL lookup requests. If a primary server is configured, the router marks the server being added as a secondary server. Parameter Description port <num> The Filtering Service port (referred to as the integration communication port) you entered during Websense installation. The default port number is 15868. timeout <secs> The amount of time the Cisco IOS router waits for a response from Websense Filtering Service. The default timeout is 5 seconds. retrans <secs> How many times the router retransmits an HTTP request when there is no response from Filtering Service. The default value is 2. ip urlfilter alert This optional setting controls system alerts. By default, system alerts are enabled. The following messages can be displayed when alerts are enabled: • %URLF-3-SERVER_DOWN: Connection to the URL filter server <IP address> is down. Deployment and Installation Center 503 Integrating Web Security with Cisco This level three LOG_ERR type message appears when a configured Filtering Service goes down. The router marks the offline server as a secondary server. It then attempts to use a defined secondary server as the primary server. If the router cannot find another Filtering Service, the URLF-3-ALLOW_MODE message is displayed. • %URLF-3-ALLOW_MODE: Connection to all URL filter servers is down and ALLOW MODE is OFF. This message appears when the router cannot find a defined Filtering Service. When the allowmode flag is set to off, all HTTP requests are blocked. • %URLF-5-SERVER_UP: Connection to a URL filter server <IP address> is made. The system is returning from ALLOW MODE. This LOG_NOTICE type message is displayed when a Filtering Service is detected as being up and the system returns from the ALLOW MODE. • %URLF-4-URL_TO_LONG: URL too long (more than 3072 bytes), possibly a fake packet. This LOG_WARNING message is displayed when the URL in a GET request is too long. • %URLF-4-MAX_REQ: The number of pending requests has exceeded the maximum limit <num>. This LOG_NOTICE message is displayed when the number of pending requests in the system exceeds the maximum limit defined. Subsequent requests are dropped. ip urlfilter audit-trail This command controls the logging of messages into the syslog server and is disabled by default. The messages logged are: • %URLF-6-URL_ALLOWED: Access allowed for URL <site’s URL>; client <IP address:port number> server <IP address:port number> This message is logged for each URL requested that is allowed by Websense software. The message includes the allowed URL, the source IP address/port number, and the destination IP address/port number. Long URLs are truncated to 300 bytes and then logged. • %URLF-6-URL_BLOCKED: Access denied URL <site’s URL>; client <IP address:port number> server <IP address:port number> This message is logged for each URL requested that is blocked by Websense software. The message includes the blocked URL, the source IP address/port number, and the destination IP address/port number. Long URLs are truncated to 300 bytes and then logged. • %URLF-4-SITE-BLOCKED: Access denied for the site <site's URL>; client <IP address:port number> server <IP address:port number> This message is logged when a request finds a match against one of the blocked domains in the exclusive-domain list. 504 Websense Web Security and Web Filter Integrating Web Security with Cisco ip urlfilter urlf-server-log This command is used to control the logging of system messages to Filtering Service and is disabled by default. To allow logging (and consequently reporting) of Internet activity on your system, you must enable this feature. When logging is enabled, the Cisco IOS router sends a log request immediately after the URL lookup request. The log message contains information such as the URL, host name, source IP address, and destination IP address. ip urlfilter exclusive-domain {permit|deny} <domain-name> This optional command is used to add a domain to, or remove a domain from, the exclusive domain list. Cisco IOS router URL filtering allows you to specify a list of domain names for which the router does not send lookup requests to Websense Filtering Service. The permit flag permits all traffic to <domain-name>. The deny flag blocks all traffic to <domain-name>. For example, if www.yahoo.com is added to the exclusive domain list, all the HTTP traffic whose URLs are part of this domain (such as www.yahoo.com/ mail/index.html, www.yahoo.com/news, and www.yahoo.com/sports) are permitted without sending a lookup request to Filtering Service. You may also specify a partial domain name. For example, you can enter .cisco.com instead of the complete domain name. All URLs with a domain name ending with this partial name (such as www.cisco.com/products, www.cisco.com/eng, people-india.cisco.com/index.html, and directory.cisco.com) are permitted or denied without having to send a lookup request to Filtering Service. When using partial domain names, always start the name with a dot (i.e., period). For example: ip urlfilter exclusive-domain permit .sdsu.edu Use the no form of this command to undo permitting or blocking of a domain name. The permitting or blocking of a domain name stays in effect until the domain name is removed from the exclusive list. Using the no form of this command removes the specified domain name from the exclusive list. For example, to stop the automatic permitting of traffic (and send lookup requests to Filtering Service) to www.example.com: no ip urlfilter exclusive-domain permit www.example.com As another example, to stop the automatic blocking of traffic to the same domain name: no ip urlfilter exclusive-domain deny www.example.com ip urlfilter allowmode {on|off} This command controls the default filtering policy if Filtering Service is down. If the allowmode flag is set to on, and the Cisco IOS router cannot find a Filtering Service, all HTTP requests are permitted. If allowmode is set to off, all HTTP requests are blocked when Filtering Service becomes unavailable. The default for allowmode is off. Deployment and Installation Center 505 Integrating Web Security with Cisco ip urlfilter max-resp-pak <number> Use this optional command to configure the maximum number of HTTP responses that the Cisco IOS router can store in its packet buffer. The default value is 200 (this is also the maximum you can specify). ip urlfilter max-request <number> Use this optional command to set the maximum number of outstanding requests that can exist at a given time. When this number is exceeded, subsequent requests are dropped. The allowmode flag is not considered in this case because it is only used when Filtering Service is down. The default value is 1000. Cisco IOS executable commands Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, and Web Security Gateway, v7.7.x These Cisco IOS router commands allow you to view configuration data and filtering information. These settings cannot be saved into the startup configuration. show ip urlfilter config This command shows configuration information, such as number of maximum requests, allowmode state, and the list of configured Filtering Services. Technical Support typically requests this information when trying to solve a problem. show ip urlfilter statistics This command shows statistics of the URL filtering feature, including: • • • • • Number of requests sent to Filtering Service Number of responses received from Filtering Service Number of requests pending in the system Number of requests failed Number of URLs blocked 506 Websense Web Security and Web Filter Integrating Web Security with Cisco debug ip urlfilter {function-trace/detailed/events} This command enables the display of debugging information from the URL filter system. Parameter Description functiontrace Enables the system to print a sequence of important functions that get called in this feature. detailed Enables the system to print detailed information about various activities that occur in this feature. events Enables the system to print various events, such as queue events, timer events, and socket events. Configuring a Cisco Content Engine Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x After Websense Web Filter or Web Security software is installed, you must activate it within the Cisco Content Engine. This configuration is done through the Cisco Webbased interface, or through a console or Telnet session. Note If load bypass or authentication bypass is enabled in the Content Engine, Internet requests that are rerouted are filtered by Websense software. See your Content Engine documentation for more information. Cisco Content Engine Web-based interface, page 508 Cisco Content Engine console or telnet session, page 509 Verifying Cisco Content Engine configuration, page 510 Configuring firewalls or routers when integrating with Cisco Content Engine, page 511 Cisco Content Engine and browser access to the Internet, page 512 Cisco Content Engine clusters, page 512 Deployment and Installation Center 507 Integrating Web Security with Cisco Cisco Content Engine Web-based interface Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x 1.

Configuring firewalls or routers when integrating with Cisco Content Engine Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter, Web Security, and Web Security Gateway, v7.7.x To prevent users from circumventing Websense filtering, your firewall or Internet router should be configured to allow outbound HTTP, HTTPS, and FTP requests only from the Cisco Content Engine. The Content Engine and Websense software transparently handle Internet requests sent from routers using Web Cache Communication Protocol (WCCP). Network Agent cannot perform protocol filtering on traffic encapsulated with WCCP. Note For Internet connectivity, Filtering Service may require authentication through a proxy server or firewall for HTTP traffic. To allow downloads of the Websense Master Database, configure the proxy or firewall to accept clear text or basic authentication. See the proxy or firewall documentation for configuration instructions. See the TRITON - Web Security Help for Master Database download instructions. Deployment and Installation Center 511 Integrating Web Security with Cisco Cisco Content Engine and browser access to the Internet Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Cisco Content Engine can regulate Internet activity either transparently or explicitly. In transparent mode, the firewall or Internet router is configured to send Internet requests to the Cisco Content Engine, which queries Filtering Service. All configuration changes can be performed through the Content Engine and any connected firewalls or routers, with no special configuration required on client computers. To run transparently, you must enable WCCP on both the Content Engine and the firewall or router. When regulating Internet activity explicitly, Web browsers on all client computers are configured to send Internet requests to the Content Engine. See Cisco Content Engine documentation for instructions. To prevent users from circumventing Websense filtering, your firewall or Internet router should be configured to allow outbound HTTP and FTP requests only from the Cisco Content Engine. To set up promptless browser authentication for NTLM or LDAP, refer to Cisco documentation. Cisco Content Engine clusters Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x If you have several Content Engines running in a cluster, you must configure each Content Engine to use Filtering Service as an HTTP, HTTPS, and FTP filter. Several Content Engines can use the same Filtering Service. See Cisco Content Engine documentation for details on setting up a cluster. 512 Websense Web Security and Web Filter 21 Integrating Web Security with Citrix Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x This section of the Websense Technical Library provides information about integrating Websense Web Filter or Web Security with Citrix® XenApp™. To have their Internet activity managed by Websense software, Citrix client computers must access the Internet through a Citrix server. Non-Citrix clients in the network can be managed as part of the same Websense deployment. See Combining Citrix with another integration, page 530, for more information. Integrating Websense Web Filter or Web Security with Citrix XenApp involves the following components: Websense Citrix Integration Service must be installed on each Citrix server to allow that server to communicate with Websense Filtering Service. Citrix Integration Service works with the following Citrix products: Product Operating System XenApp 6.0 Windows Server 2008 R2 XenApp 5.0 Windows Server 2008 (32- and 64-bit) Websense Filtering Service interacts with Citrix Integration Service and Network Agent to determine whether to block or permit Internet requests. Websense Network Agent manages Internet protocols not managed by your Citrix server integration. If your Citrix server runs applications that use protocols other than HTTP, FTP, or SSL, Network Agent can apply protocol filtering to those applications based on a computer or network policy, or the Default policy. It cannot apply user- and group-based policies to protocol filtering of applications running on the Citrix server. Deployment and Installation Center 513 Integrating Web Security with Citrix See the following for information about integrating with Citrix products: Filtering Citrix server users, page 516 Citrix Integration Service installation overview, page 519 Upgrading Citrix Integration Service to 7.7, page 528 Configuring user access on Citrix servers, page 529 Initial Setup of Citrix integration, page 530 Deployment considerations for integration with Citrix products Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Websense software integrated Citrix XenApp can monitor HTTP, FTP, and SSL requests from individual Citrix users. Network Agent can be used to filter other protocols, if needed. For the XenApp versions supported by Websense software, see System requirements for this version, page 2. The following illustration shows a typical deployment used to filter both users who access the Internet through a Citrix server and users who access the Internet locally. The Websense filtering components are installed on a dedicated machine that can filter Citrix server clients (non-Citrix clients are filtered by a separate integration product or Network Agent; see Integrating Web Security with Citrix, page 513). The Websense Citrix Integration Service must be installed on each Citrix server to allow it to communicate with Filtering Service. No other Websense components can be installed on a Citrix server. Separate Network Agent instances are needed for the Citrix and non-Citrix users. To simplify the diagram, not all individual Websense components are shown. Other integrations also can be used in the non-Citrix portion of the network. See Integrating Web Security with Citrix, page 513, for Websense software configuration instructions. The diagram provides a general overview and best practice location for your integration product, but does not show all Websense components. Larger networks require Websense components to be distributed across several dedicated machines. 514 Websense Web Security Solutions Integrating Web Security with Citrix Other integrations for Web Security Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Check the list of Websense Technology Partners at www.websense.com/global/en/ Partners/TAPartners/SecurityEcosystem/ to see if Websense software can be integrated with a third-party product.

Larger networks require Websense components to be distributed across several dedicated machines. Filtering Citrix server users Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Filtering both Citrix and nonCitrix users, page 518 When Websense Web Filter or Web Security is integrated with Citrix: A recommended maximum of 10 Citrix servers can be connected to one Websense Filtering Service. This number can be configured and depends on the user load. Multiple Filtering Services are needed if more than 15 Citrix servers are used, with each Citrix server handling about 20 to 30 Citrix users. The Filtering Service and Websense Network Agent monitoring Citrix traffic should be installed on a dedicated machine, and not on a Citrix server. The Filtering Service and Network Agent instances monitoring Citrix traffic use the same Policy Broker, Policy Server, User Service, and so on as Filtering Service and Network Agent instances used to monitor non-Citrix traffic. Separate Filtering Service and Network Agent instances must be used to monitor non-Citrix traffic. Do not configure a separate integration product to filter HTTP, HTTPS, FTP, or SSL requests from Citrix servers. If you want to use Network Agent to filter protocol traffic from the Citrix servers: Network Agent must be located where it can see all of the traffic between the Citrix servers and the Filtering Service instances. For example, the machine running Network Agent could be connected to a span port on the same network switch as the machines running Filtering Service. If the Citrix server is configured to use virtual IP addresses, configure Network Agent to monitor the entire range of the IP addresses. Also, a single policy should be set for this range. See the “Network Configuration” topic in the TRITON - Web Security Help for instructions on configuring IP ranges for Network Agent. 516 Websense Web Security Solutions Integrating Web Security with Citrix If you have standalone instances of Filtering Service (not configured to integrate with Citrix or any other integration product), use a dedicated instance of Network Agent to monitor users of the Citrix servers. Do not monitor non-Citrix traffic with this Network Agent. While Network Agent can be used to filter protocols for Citrix, user-based and group-based policies cannot be applied. Policies can be applied to individual computers and network ranges, identified by IP addresses or IP address ranges. Otherwise, the Default policy is applied to all users. Also, Network Agents monitoring non-Citrix traffic (users who access the Internet without going through a Citrix server) must not be used to monitor Citrix traffic. This diagram shows a typical deployment to filter users who access the Internet through a Citrix server. To simplify the diagram, not all individual Websense components are shown. The main Websense filtering components are installed on a separate, dedicated machine that can communicate with all of the Citrix server machines, and non-Citrix users, if applicable. The Websense Citrix Integration Service must be installed on each Citrix server to allow it to communicate with Filtering Service. No other Websense components should be installed on the Citrix server machines. Deployment and Installation Center 517 Integrating Web Security with Citrix Filtering both Citrix and non-Citrix users If your network includes some users who access the Internet via a Citrix server, and others who access the Internet through another gateway (firewall, caching appliance, or proxy server), the integrations can be configured to work together. To install the Citrix Integration Service on a Citrix Server, see page 520. If you have Citrix users and non-Citrix users in your network, the same Websense components, except for Network Agent, can be used for both sets of users. A separate installation of Network Agent is needed for the Citrix users. See Install Filtering Service and Network Agent to integrate with Citrix for instructions. To install Websense Web Filter or Web Security for non-Citrix users, refer to the appropriate section of this Deployment and Installation Center for that integration product. To configure the Websense components installed with the non-Citrix integration to communicate with Citrix, refer to the section pertaining to your integration in Combining Citrix with another integration, page 530. 518 Websense Web Security Solutions Integrating Web Security with Citrix Citrix Integration Service installation overview Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x There are 5 general steps involved in configuring Websense Web Security solutions to integrate with Citrix: 1. Install one or more instances of Websense Filtering Service to integrate with Citrix. 2. Install a dedicated Websense Network Agent to monitor the Citrix servers. To perform the first 2 steps, see Install Filtering Service and Network Agent to integrate with Citrix, page 519. 3. Obtain the Citrix configuration package (used to install the Citrix Integration Service configuration utility). See Obtain the Citrix Integration Service configuration package, page 520. 4. Create and configure a Citrix Integration Service installation package for your deployment. See Configure the Citrix Integration Service installation package, page 521. 5. Use the installation package to install Citrix Installation Service on your Citrix servers. See Use the installation package to install Citrix Integration Service on a Citrix server, page 526. For information about upgrading a prior-version Citrix Integration Service, see Upgrading Citrix Integration Service to 7.7, page 528. If Websense software will manage Internet activity for both Citrix and non-Citrix users, refer to Combining Citrix with another integration, page 530, after installing the Websense Citrix Integration Service. Install Filtering Service and Network Agent to integrate with Citrix Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Deployment and Installation Center 519 Integrating Web Security with Citrix Before performing these steps, Websense Policy Broker and Policy Server must already be installed and running in your network. You will be prompted for Policy Server connection information during Filtering Service installation. 1. Install an instance of Websense Filtering Service to integrate with Citrix as follows: a. Launch the Websense Unified Installer on a machine other than the Citrix server and select a Custom installation. b. On the Custom Installation screen, next to Web Security, click Install or Modify. c. Select Filtering Service as the component to install. d. On the Integration Option screen, select Integrated with another application or device. e. On the Select Integration screen, select Citrix.

Make sure you are launching the correct version. 3. In the Profile Source screen, click Browse and select the folder containing either the default Citrix installation package template or an existing installation package that you want to modify, then click Next. If the following message appears, make sure all necessary files are present in the folder you specified: The selected installation package does not include all of the necessary files. The folder you specify must contain all of the files extracted from the Citrix configuration package in step 1. 4. In the Connections screen, configure Filtering Service connection behavior for Citrix Integration Service as described below. When you are finished, click Next. a. If 127.0.0.1:15868 appears (as shown above), select it and then click Remove. Filtering Service should never be installed on the Citrix server machine itself. 522 Websense Web Security Solutions Integrating Web Security with Citrix b. Under Connection Details, enter the IP address or hostname of a Filtering Service machine, then enter the filtering port (15868 by default). Note The Filtering Service port must be in the range 102465535. To determine what port is used by Filtering Service, check the eimserver.ini file—located in C:\ Program Files or Program Files (x86)\Websense\Web Security\bin (Windows) or /opt/Websense/bin/ (Linux)— on the Filtering Service machine. In this file, look for the WebsenseServerPort value. Important: Do not modify the eimserver.ini file. c. Click the right arrow (>) to add the IP address/hostname and port entry to the list to the right. d. Repeat the previous 2 steps for each Filtering Service instance you want used by the Citrix server. When multiple Filtering Service instances are specified, if the first instance is unavailable, Citrix Integration Service attempts communication with the next instance in the list. If no Filtering Service instances are available, Citrix Integration Service continues to attempt communication in the background every 1 minute. Until communication is established, Citrix Integration Service fails open (permits all requests) or fails closed (blocks all requests) depending on your select in step f (below). Note Each Filtering Service instance tracks continue, quota, and password override information independently. If the Citrix Integration Service fails over from one Filtering Service instance to another, usage quotas may be different and override passwords may need to be entered again. e. Enable or disable the Do not send user name information to Filtering Service option. If this option is selected (enabled), user name information for Citrix users is not included in reports. The setting applies to all Filtering Service instances listed. f. Enable or disable the Block all HTTP/HTTPS/FTP traffic if unable to connect to a Filtering Server option to determine whether Citrix Integration Service blocks or permits all requests when it cannot communicate with Filtering Service. Deployment and Installation Center 523 Integrating Web Security with Citrix 5. In the Client Settings screen, select options as described below. When you are finished, click Next. Notify users when HTTPS or FTP traffic is blocked: Determine whether users see a browser pop-up message when HTTPS or FTP traffic is blocked. If so, also specify the how long the pop-up message remains visible. Protect installation directory from modification or deletion: This option prevents tampering with the Citrix Integration Service on the Citrix server. Attempts to delete it, replace files, or modify registry entries are stopped. 6. On the Trusted Sites screen, specify those URLs or domains that should not be filtered as explained below. When you are finished, click Next. To add a URL or regular expression, click Add, then enter either a URL or a regular expression specifying a set of URLs. Any regular expression adhering to 524 Websense Web Security Solutions Integrating Web Security with Citrix ISO/IEC TR 19768 (within the character-number limit) is valid.

Deployment and Installation Center 529 Integrating Web Security with Citrix Initial Setup of Citrix integration Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Configuring for Citrix Virtual IP Addresses, page 530 Combining Citrix with another integration, page 530 Deployment scenarios, page 530 Deploying with Network Agent, page 531 Configuration, page 531 Configuring the non-Citrix integration, page 531 Configuring for Citrix Virtual IP Addresses If an integrated Citrix server is configured to use virtual IP addresses, you must configure Network Agent to monitor the entire range of the IP addresses. You should also set a single Websense filtering policy for this range of virtual IP addresses. See the “Network Configuration” topic in the TRITON - Web Security Help for instructions on adding and editing IP address ranges for Network Agent, and configuring policies for specific IP address ranges. Combining Citrix with another integration Websense Web Security solutions can be set up to filter both Citrix and non-Citrix users. This section provides instructions for configuring Websense software to work with the Citrix integration product. Deployment scenarios The corporate network (non-Citrix users) can access the Internet through Websense Network Agent, Content Gateway, or a third-party integration product, such as Cisco® PIX® or Microsoft® Forefront TMG. The component or integration product sends Internet requests to Websense Filtering Service to determine whether to block or permit the request. Citrix clients access the network through Citrix XenApp. Depending on the number of Citrix users, the access may be through one server, or through a server farm consisting 530 Websense Web Security Solutions Integrating Web Security with Citrix of multiple Citrix servers. For more information, see Filtering Citrix server users, page 516. Websense filtering is accomplished by installing the Websense Citrix Integration Service on each Citrix server. See Citrix Integration Service installation overview, page 519, for instructions. In lower volume networks, each Integration Service communicates with the same Filtering Service. The non-Citrix users can be pointed to the same instance of Filtering Service as the Integration Service. Deploying with Network Agent If you have a standalone deployment of Websense Web Filter or Web Security, separate instances of Network Agent are needed for the Citrix and non-Citrix users. See Standalone Websense Web Filter or Web Security configuration, page 533, for configuration information. Configuration To use a Websense Web Security solution to filter both Citrix users and users accessing the Internet through Network Agent or another integration product, the nonCitrix-related components must be installed and running before the Citrix integration is completed. 1. Install your Web Security solution. 2. Install the Filtering Service and Network Agent to be used for Citrix integration. 3. Configure and iinstall the Websense Citrix Integration Service on each Citrix server. This component sends requests from Citrix clients to Filtering Service for filtering. Up to 10 Integration Services can be pointed to the same Filtering Service. If more than 10 Citrix servers are deployed, then additional Filtering Services can be used. See Citrix Integration Service installation overview, page 519, for instructions for steps 2 and 3. 4. Configure the non-Citrix integration product to ensure that requests coming from the Citrix clients are not filtered twice. See Configuring the non-Citrix integration, page 531. Configuring the non-Citrix integration Before the integrations can be used together, the non-Citrix integration must be set up to prevent Internet requests sent via the Citrix servers from being filtered twice. A request from a Citrix client is passed to the Citrix server. The Citrix Integration Service sends the request to Filtering Service, which determines whether to block or permit the request. Simultaneously, the Citrix server sends the same request to the non-Citrix integration, which must be configured to allow the request to pass through. Deployment and Installation Center 531 Integrating Web Security with Citrix Cisco PIX configuration Use a console or TELNET session to configure your Cisco PIX Firewall (security appliance). This configuration has been tested for Cisco PIX version 6.3 and later. 1. Access the security appliance and enter your password. 2. Put the security appliance into privilege EXEC mode by entering enable, followed by your enable password. 3. To activate the configure mode, enter: configure terminal Note For help with individual commands, enter help followed by the command. For example, help filter shows the complete syntax for the filter command, and explains each of the options. 4. Use the filter url except command with the IP address or addresses for the Citrix servers to disable the second filtering by Websense Web Filter or Web Security of requests from Citrix users. For a group of Citrix servers in a server farm, you can enter a range: filter url except <IP address range> For one or two Citrix servers, you can add the commands individually: filter url except <internal IP address> <internal subnet mask> <external IP address> <external subnet mask> Here, the internal IP address and subnet mask refer to the Citrix server, and the external IP address and subnet mask are for a secondary machine, other than the PIX firewall, that is used for Internet access. The external settings are generally set to zero: 0.0.0.0 0.0.0.0. 5. Type exit to leave configure mode. See Cisco’s PIX documentation and the Websense Technical Library (www.websense.com/library) for more information on this integration. Check Point FireWall-1 configuration To configure Check Point FireWall-1 to work properly with a Citrix integration, you must define a rule on FireWall-1 to allow requests from the Citrix server to pass to the Internet without sending those requests to Websense Web Filter or Web Security for filtering. Use the Firewall-1 SmartDashboard™ (or Policy Editor in older versions) to add the Citrix Presentation Servers to the Allow Rule. Do not add the Presentation Servers to the Block rule. 532 Websense Web Security Solutions Integrating Web Security with Citrix See Check Point’s FireWall-1 documentation and the Websense Technical Library (www.websense.com/library) for more information. Microsoft Forefront TMG configuration The Websense ISAPI plug-in must be set to ignore traffic from the Citrix servers. This configuration is done by adding the host name of each Citrix server to the isa_ignore.txt file on the Microsoft Forefront TMG (TMG) machine. Also, ensure that none of the Citrix servers are set to use the TMG machine as a proxy server. 1. On the TMG machine, go to the WINDOWS\system32 directory and open the isa_ignore.txt file in a text editor. Note The default isa_ignore.txt file installed with Websense software contains the following URL: url=http://ms_proxy_intra_array_auth_query/ Do not delete this URL. It is used by TMG machines in a CARP array for communication. This URL must be ignored to allow filtering and logging to work properly when multiple TMG instances are deployed in an array. 2. Enter the host name for each Citrix server on its own line in the isa_ignore.txt file. Important You must enter each host name in the exact same format that ISA/TMG passes it to Filtering Service. Use the following format: hostname=<Citrix_server_hostname> Replace <Citrix_server_hostname> with the name of the Citrix server machine. 3. Restart the TMG machine. See Microsoft’s ISAPI documentation and the Websense Technical Library (www.websense.com/library) for more information. Standalone Websense Web Filter or Web Security configuration In a standalone Websense Web Filter or Web Security deployment, separate instances of Network Agent must be installed to filter Citrix and non-Citrix users. The Network Agent monitoring non-Citrix users must be set to ignore the Citrix servers. This configuration allows protocol filtering of both Citrix and non-Citrix requests. 1. Open TRITON - Web Security, and go to Settings > Network Agent. Deployment and Installation Center 533 Integrating Web Security with Citrix 2. In the left navigation pane, select the IP address of the NIC used for monitoring Internet requests to open its Local Settings page. 3. Under Monitor List Exceptions, add each Citrix server that Network Agent should exclude from monitoring. a. To identify a machine, click Add, and then enter the Citrix server’s IP address, or a range of IP addresses for a group of Citrix servers in a server farm. Then, click OK. b. Repeat this process until all Citrix servers have been added, either individually or as part of a range. 4. Click OK to cache your changes and return to the NIC Settings page. Changes are not implemented until you click Save and Deploy. See the “Network Configuration” topic in the TRITON - Web Security Help for instructions on configuring NIC settings. 534 Websense Web Security Solutions 22 Integrating Web Security with Microsoft Products Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x This section of the Deployment and Installation Center provides information specific to integrating Websense Web Security solutions with Microsoft® Forefront™ Threat Management Gateway (TMG) 2010 or later. Refer to Installation overview: Web Filter and Web Security, page 193, as your primary source of installation instructions. Only additional or alternate steps required to enable TMG integration are provided here. An integration with TMG affects the following Websense components: Websense ISAPI Filter plug-in: This additional Websense component is installed on the machine running TMG. The ISAPI Filter plug-in configures TMG to communicate with Websense Filtering Service. Websense Filtering Service: Interacts with TMG and Websense Network Agent to filter Internet requests. Filtering Service either permits the Internet request or sends an appropriate block message to the user. After the Filtering Service is installed, the ISAPI Filter plug-in must be installed on every TMG machine in your network. Websense Network Agent: Manages Internet protocols that are not handled by TMG. Network Agent also enables bandwidth-based filtering. If your environment includes an array of TMG machines, install Websense Web Security components on a machine outside the array. When TMG receives an Internet request from a user, it passes the request to Websense Filtering Service, which determines the category assigned to the URL and checks the policy assigned to the client. If the site is assigned to a blocked category, the client receives a block page instead of the requested site. If the site is assigned to a permitted category, Filtering Service notifies TMG that the site is not blocked, and the client is given access to the site. Deployment and Installation Center 535 Integrating Web Security with Microsoft Products The following topics discuss the various aspects of integrating with TMG: Deployment considerations for integration with Forefront TMG, page 536 Installing Web Security to integrate with Forefront TMG, page 539 Upgrading Web Security when integrated with ISA Server or Forefront TMG, page 542 Removing the ISAPI Filter Plug-In, page 542 Converting to an integration with Forefront TMG, page 544 Forefront TMG initial setup, page 545 User identification and authentication with Forefront TMG, page 551 Deployment considerations for integration with Forefront TMG Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Single Microsoft Forefront TMG configuration, page 536 Array configuration, page 537 Single Microsoft Forefront TMG configuration The following illustration shows placement of Websense filtering components on 2 dedicated machines, separate from the Microsoft Forefront TMG server. The ISAPI Filter must be installed on the TMG machine so that Internet activity information can be communicated to Filtering Service. 536 Websense Web Security and Web Filter Integrating Web Security with Microsoft Products The Filtering Service and TMG machines must be able to communicate over the network. The diagram provides a general overview and best practice location for your integration product, but does not show all Websense components. Larger networks require Websense components to be distributed across several dedicated machines. Array configuration Websense software is compatible with most array configurations, including Cache Array Routing Protocol (CARP) arrays. It is a best practice to install Websense software outside an array of Forefront TMG machines. Install the Websense ISAPI Filter on each member of the array. See the following illustration. Deployment and Installation Center 537 Integrating Web Security with Microsoft Products When Websense software is deployed in this configuration, all array members send Internet requests to Filtering Service outside the array. Other configurations are possible. See your Microsoft Forefront TMG documentation for information about TMG configurations. The diagram provides a general overview and best practice location for your integration product, but does not show all Websense components. Larger networks require Websense components to be distributed across several dedicated machines. 538 Websense Web Security and Web Filter Integrating Web Security with Microsoft Products Installing Web Security to integrate with Forefront TMG Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Installing the ISAPI Filter plug-in for Forefront TMG, page 539 The general process of installing Websense Web Security solutions to integrate with Microsoft Forefront TMG is as follows: 1. Begin by installing Web Security policy, management, and reporting components in your network (not on the TMG machine). See Installation overview: Web Filter and Web Security, page 193, for instructions. Websense Filtering Service must already be installed before the ISAPI Filter plug-in is installed on the TMG machine. When installing Filtering Service, specify that it is integrated with TMG. 2. Install the ISAPI Filter plug-in on the TMG machine (as described below). The Forefront TMG plug-in installer, rather than the TRITON Unified Installer, is used to install the ISAPI plug-in for Forefront TMG, as described in the next section. The only Websense components installed on the Forefront TMG machine are the ISAPI Filter plug-in and Websense Control Service (which manages installation and removal of Websense software components). Installing the ISAPI Filter plug-in for Forefront TMG The Forefront TMG plug-in installer is used to install the Websense ISAPI Filter plugin for Forefront TMG on the TMG machine. Deployment and Installation Center 539 Integrating Web Security with Microsoft Products Websense Filtering Service must be installed and running before you install the ISAPI Filter plug-in. Make sure that Forefront TMG integration was specified during Filtering Service installation. Important The ISAPI Filter plug-in for Forefront TMG is supported on only Windows 2008 R2. As part of the installation process, you must stop the Microsoft Forefront TMG Firewall service (Firewall service). Because this may stop network traffic, perform the installation during a time when a stoppage will least affect your organization. Do not stop the Firewall service until instructed to do so by the installer. Port 55933 (Websense Control Service communication port) must be open locally, for the ISAPI Filter plug-in to be installed successfully. Before beginning the installation process: Download or copy the Forefront TMG plug-in installer to this machine. This installer is available at mywebsense.com. Close all applications and stop any antivirus software. To perform the installation: 1. Start the Forefront TMG plug-in installer. When the Introduction screen displays, click Next. 2.

Forefront TMG initial setup Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x If you installed Web Security Log Server, see Enabling communication with the Log Database when integrated with Forefront TMG, page 546. Deployment and Installation Center 545 Integrating Web Security with Microsoft Products Websense software filters HTTP, HTTPS, and FTP requests sent to TMG, but cannot filter traffic tunneled over a SOCKS or WinSOCK proxy server. To use Websense filtering in a network that uses a SOCKS or WinSOCK proxy server, you can either: Disable the WinSOCK or SOCKS service. Use the WinSOCK or SOCKS proxy client to disable the specific protocols that you want Websense software to filter (HTTP, HTTPS, and FTP), then configure browsers on client computers to point to TMG for each of these protocols. For information about disabling a protocol, see the TMG Help from Microsoft. Additional configuration of the Websense ISAPI Filter is required if you are using non-Web proxy clients with TMG. These TMG clients include the Firewall/ Forefront TMG Client with proxy server disabled, and SecureNAT clients. See Configuring for TMG using non-Web-Proxy clients, page 547, for instructions. To configure Websense software to ignore certain traffic based on the user name, host name, or URL, see Configuring the ISAPI Filter plug-in to ignore specific traffic, page 549, for instructions. If Network Agent was installed, configure Network Agent with the IP addresses of all proxy servers through which computers route their Internet requests. See Network Configuration in the TRITON - Web Security Help for instructions. If you installed Remote Filtering Server in your Websense deployment, configure TMG to not monitor (i.e., ignore) the machine on which Remote Filtering Server is installed. If TMG monitors this machine, it could interfere with remote filtering. See your TMG documentation for instructions. Enabling communication with the Log Database when integrated with Forefront TMG Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x When you install Web Security Log Server, TMG must be configured to permit communication with the Log Database.

The term non-Web-Proxy clients refers to: Firewall/Forefront TMG Client with the proxy server disabled SecureNAT clients Firewall/Forefront TMG Client If you are using Firewall/Forefront TMG Client with Forefront TMG, and the proxy server is enabled (default setting), Websense software filters Internet requests normally. However, if the proxy server is disabled, Websense software cannot filter Internet requests without additional configuration. Check the Firewall/Forefront TMG Client machine to see if the proxy server is disabled. 1. Open the Firewall/Forefront TMG Client configuration screen, and select the Web Browser tab. Deployment and Installation Center 547 Integrating Web Security with Microsoft Products 2. View the Enable Web browser automatic configuration check box. If it is marked, the proxy server is enabled. Websense software requires no additional configuration. If it is cleared, the proxy server is disabled. See Configuring the ISAPI Filter plug-in, page 548, for additional configuration steps. Note If the proxy server is disabled, then Websense software filters HTTP only; it cannot filter HTTPS. SecureNAT clients SecureNAT clients require that you configure the default gateway so that all traffic to the Internet is sent through TMG. If you need information about configuring and using SecureNAT clients, see your TMG documentation. See Configuring the ISAPI Filter plug-in, page 548, for additional configuration steps. Configuring the ISAPI Filter plug-in If you are using the TMG Firewall Client with the proxy server disabled, or SecureNAT clients, the ISAPI Filter plug-in must be configured to ignore requests going directly to the TMG and to filter only those requests going out to the Internet. Note If you are using the TMG Server Firewall Client with the proxy server disabled, then Websense software filters HTTP only; it will not be able to filter HTTPS. 1. On the TMG machine, create a file called ignore.txt in the Windows system32 directory. 2. Enter the hostname or IP address of the TMG machine in the text file. Host names must be entered in ALL CAPS. Entries that are not in all capital letters are not used. 3. If the TMG machine hosts multiple Web sites, add the names of all the Web sites being hosted. For example: webmail.rcd.com. If only one Web site is hosted, do not add it to this file. 4. Restart the TMG machine. 548 Websense Web Security and Web Filter Integrating Web Security with Microsoft Products Configuring the ISAPI Filter plug-in to ignore specific traffic Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: In this topic Web Filter and Web Security, v7.7.x Configuring the ISAPI Filter plug-in to ignore specific traffic, page 549 Client computer configuration, page 550 Firewall configuration, page 550 Configuring the ISAPI Filter plug-in to ignore specific traffic You can configure the ISAPI Filter plug-in to bypass both filtering and logging for certain traffic, based on the user name, host name, or URL. This may be used for a small group of Web sites or users, or for machines in a complex proxy-array or proxychaining configuration. To prevent filtering and logging of this traffic, add the user names, host names, and URLs that you do not want Websense software to filter to the isa_ignore.txt file. 1. On the TMG machine, open the isa_ignore.txt file in a text editor. This file is located in the Windows system32 directory. Important The default isa_ignore.txt file installed during a Websense upgrade or installation contains the following URL: url=http://ms_proxy_intra_array_auth_query/ Do not delete this URL. It is used by TMG in a CARP array for communication. This URL must be ignored by Websense software to allow filtering and logging to work properly when multiple TMG instances are deployed in an array. 2. Enter each user name, hostname, or URL that you want Websense software to ignore. Enter each item on its own line in the file, using the formats below. User name: Enter the name of a user whose Internet requests should not be filtered or logged by Websense software: username=<user_name> Deployment and Installation Center 549 Integrating Web Security with Microsoft Products Examples: username=jsmith username=domain1/jsmith Hostname: Enter a destination hostname that Websense software should not filter or log user visits to: hostname=<name> Example: hostname=yahoo.com URL: Enter a URL that Websense software should not filter or log user visits to: url=<URL> Example: url=http://mail.yahoo.com/ url=mail.yahoo.com/ Note To assure that the correct format is available for all situations, it is recommended that you enter the same name in all available configurations. For example, make 2 entries for user name: one with and one without the domain. Make 2 entries for URL: one with and one without the protocol. 3. Restart the TMG service. Client computer configuration Internet browsers on client computers should be configured to use TMG to handle HTTP, HTTPS, and FTP requests. An exception to this configuration is browsers in an TMG environment using Firewall/Forefront TMG Clients or SecureNAT. These browsers must point to the same port, 8080, that TMG uses for each protocol. See the browser online help for configuration instructions. Firewall configuration To prevent users from circumventing Websense filtering, configure your firewall or Internet router to allow outbound HTTP, HTTPS, and FTP requests only from TMG. 550 Websense Web Security and Web Filter Integrating Web Security with Microsoft Products Contact your router or firewall vendor for information about configuring access lists on the router or firewall. Important If Internet connectivity of Websense software requires authentication through a proxy server or firewall for HTTP traffic, the proxy server or firewall must be configured to accept clear text or basic authentication to enable the Websense Master Database download. User identification and authentication with Forefront TMG Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic TMG clients, page 552 Firewall/Forefront TMG and SecureNAT clients, page 552 Web Proxy clients, page 552 Authentication Methods, page 553 Transparent identification, page 555 In order to apply user and group-based policies to Internet requests, Websense Filtering Service must receive information about the user making the request. If no user information is available, Websense software can still apply IP address-based policies, or the Default policy. To ensure that Filtering Service receives user information, you can: Enable authentication within TMG. Install a Websense transparent identification agent (DC Agent, Logon Agent, eDirectory Agent, or RADIUS Agent). Enable manual authentication within Websense software. Users who cannot be identified by other means are prompted for logon information when they open a browser. See “Manual Authentication” in the TRITON - Web Security Help for more information. Deployment and Installation Center 551 Integrating Web Security with Microsoft Products TMG clients These TMG clients are supported: Firewall/Forefront TMG (see Firewall/Forefront TMG and SecureNAT clients, page 552) SecureNAT (see Firewall/Forefront TMG and SecureNAT clients, page 552) Web Proxy (see Web Proxy clients, page 552) The term clients in this environment refers to computers or applications that run on computers and rely on a server to perform some operations. Each type of client can be configured so that Websense software can obtain user identification and filter Internet requests based on user and group policies. Firewall/Forefront TMG and SecureNAT clients Firewall/Forefront TMG and SecureNAT clients cannot identify users transparently without special settings. These clients require a Websense transparent identification agent to authenticate users. To enable user-based filtering policies with these clients, select one of these options: Configure computer browsers to access the Internet through TMG. This configuration allows Firewall/Forefront TMG and SecureNAT clients to also work as Web Proxy clients. If you choose this option, see Web Proxy clients for more information. If you are using a Windows-based directory service, disable all authentication methods within TMG and use Websense transparent identification. This method allows Websense Filtering Service to obtain user identification from the network’s directory services. See Transparent identification, page 555, for more information. Enable Websense software to prompt users for authentication (manual authentication). This method allows Websense software to obtain the user information it needs if neither the TMG nor a Websense transparent identification agent provides the information. See “Manual Authentication” in the TRITON - Web Security Help for more information. Web Proxy clients After the browser is configured to use TMG as a proxy server, Web Proxy clients send Internet requests directly to TMG. You can assign individual user or group policies with one of the following methods. If your network uses only Microsoft Internet Explorer® browsers, version 5.0 or later, you can enable Integrated Windows Authentication within TMG to identify users transparently. 552 Websense Web Security and Web Filter Integrating Web Security with Microsoft Products If you are using a Windows-based directory service with various browsers, you can identify users transparently by disabling all authentication methods within TMG and implementing Websense transparent identification. See Transparent identification, page 555, for more information. If the network uses a mixture of browsers, you can enable one or more of TMG’s authentication methods. Some of these methods may require users to authenticate manually for certain older browsers. See Authentication Methods, page 553, for more information. Enable Websense software to prompt users for authentication (manual authentication). This method allows Websense software to obtain the user information it needs if neither TMG nor a Websense transparent identification agent provides the information. See “Manual Authentication” in the TRITON - Web Security Help for more information. Authentication Methods TMG provides 4 methods of authentication: Basic authentication Digest authentication Integrated Windows authentication (enabled by default) Client Certificate authentication Microsoft Internet Explorer, version 5.0 and later, supports all of these authentication methods. Other Web browsers may support only Basic authentication. When no authentication method is enabled in TMG, it does not pass Websense software any information about who is making the Internet request. When this occurs, you can: Filter with computer and network policies. Enable Websense manual authentication to permit user-based filtering. See “Manual Authentication” in the TRITON - Web Security Help for more information. Enable Websense transparent identification to permit user-based filtering. See Transparent identification, page 555, for more information. Basic authentication Basic authentication prompts users to authenticate (log on) each time they open a browser. This authentication allows TMG to obtain user identification, regardless of the browser, and send the information to Websense software, which filters Internet requests based on individual user and group policies. If Basic authentication is enabled in combination with Integrated Windows authentication: Deployment and Installation Center 553 Integrating Web Security with Microsoft Products Users with Microsoft Internet Explorer browsers are transparently identified. Users with other browsers are prompted for a user name and password. Digest authentication Digest authentication is a secure authentication method used in Windows Server 2003 domains. The features are the same as Basic authentication, but the user name and password are scrambled when they are sent from the browser to TMG. The user can authenticate to TMG without the user name and password being intercepted. User information is sent to Websense software, which then filters Internet requests based on individual user and group policies. If Digest authentication is enabled in combination with Integrated Windows authentication: Users with Microsoft Internet Explorer browsers are transparently identified. Users with other browsers are prompted for a user name and password. Integrated Windows authentication Integrated Windows authentication provides secure authentication. With this authentication enabled, TMG obtains user identification transparently from browsers using Microsoft Internet Explorer 5.0 and later. User information is sent to Websense software, which then filters Internet requests based on individual user and group policies. If your network has a mixture of Microsoft Internet Explorer browsers and other browsers, you can enable both Basic and Integrated Windows authentication, or Digest and Integrated Windows authentication. In either configuration: Users with Microsoft Internet Explorer browsers are identified transparently. Users with other browsers are prompted for a user name and password. Note To transparently identify all users in a mixed browser environment, you can disable Basic or Digest authentication and use Websense transparent identification (see Transparent identification, page 555) in conjunction with Integrated Windows authentication. 554 Websense Web Security and Web Filter Integrating Web Security with Microsoft Products Client Certificate authentication Client Certificate authentication identifies users requesting information about a Web site. If Client Certificate is used, TMG requests the certificate and verifies that it belongs to a client that is permitted access, before allowing the Internet request. Note To use Websense transparent identification, you must disable Client Certificate authentication. Before changing authentication methods, consider the impact of the change on other TMG functions. For more information about TMG authentication and how to configure these authentication methods, see Microsoft’s documentation. Transparent identification Websense transparent identification agents (DC Agent, Logon Agent, eDirectory Agent, and RADIUS Agent) allow Websense software to apply user and group based policies to Internet requests without prompting users to authenticate in the browser. If TMG is not configured to send user information to Filtering Service, you can use a Websense transparent identification agent to identify HTTP and non-HTTP users. If TMG provides user information for HTTP(S) requests, you can still use a Websense transparent identification requests to obtain user and group information for other protocol requests, managed by Websense Network Agent. See Installation overview: Web Filter and Web Security, page 193, for instructions on installing individual Websense components. See User Identification in the TRITON Web Security Help for information about configuring transparent identification agents. Websense software also offers secure manual authentication with Secure Sockets Layer (SSL) encryption to protect user names and passwords being transmitted between client computers and Filtering Service. See “Secure Manual Authentication” in the TRITON - Web Security Help for more information and instructions on activating this feature. Deployment and Installation Center 555 Integrating Web Security with Microsoft Products Troubleshooting integration with Forefront TMG Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic SecureNAT clients are not being filtered, page 556 No filtering occurs after the ISAPI Filter plug-in is installed, page 556 SecureNAT clients are not being filtered If you are using non-Web proxy clients (for example, Firewall Client with proxy server disabled, or SecureNAT clients) with TMG, additional configuration of the Websense ISAPI filter is required.

No filtering occurs after the ISAPI Filter plug-in is installed If users are not being filtered after the Websense ISAPI Filter plug-in has been installed on the Forefront TMG machine, the plug-in may not be able to communicate with Websense Filtering Service. Verify that the ISAPI Filter plug-in is using the correct Filtering Service information. 1. Go to the Windows system32 directory and open the wsMSP.ini file. 2. Under [initSection], check the EIMServerIP and EIMServerPort parameters (these are the Filtering Service IP address and port, respectively). For example: [initSection] EIMServerIP=10.203.136.36 EIMServerPort=15868 The default port is 15868. 556 Websense Web Security and Web Filter 23 Integrating Web Security using ICAP Service Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Websense ICAP Service makes it possible to integrate Websense Web Security solutions with third-party proxies and proxy-caches that support communication with ICAP servers. Integration via ICAP affects the following Websense components: Websense ICAP Service is installed with Filtering Service. It includes an ICAP server that enables third-party proxies to communicate with Filtering Service. Websense Filtering Service interacts with ICAP Service and Network Agent to filtering Internet requests passed from the proxy via ICAP. For installation instructions, see Installing Web Security to integrate with ICAP Service, page 558. After installing Websense software, configure your proxy to communicate with Websense ICAP Service (see Configuring the proxy to communicate with ICAP Service, page 559). The Websense service may also require configuration (see Configuring ICAP Service, page 560) if the default settings are not appropriate for your environment. To be filtered by Websense software, a computer must access the Internet through the integrated proxy. When the proxy receives an Internet request, it uses ICAP to query Websense ICAP Service to find out if the request should be blocked or permitted. ICAP Service queries Filtering Service, which checks the policy assigned to the client and either serves a block page or notifies the proxy to permit the request. Deployment and Installation Center 557 Integrating Web Security using ICAP Service Installing Web Security to integrate with ICAP Service Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Installation overview, page 558 Converting a standalone installation to use ICAP integration, page 558 Installation overview The Websense ICAP Service is installed with Filtering Service.

Upgrade to the current version (if you are not already using the current version), then restart the Filtering Service machine. 2. Uninstall the existing instance of Filtering Service and Network Agent. 3. Reinstall Filtering Service to integrate with ICAP Service. Also reinstall Network Agent. The components can be reinstalled at the same time if they are on the same machine. If the components are on separate machines, first reinstall Filtering Service, then reinstall Network Agent. 4. Configure your ICAP integration. See: Configuring the proxy to communicate with ICAP Service, page 559 558 Websense Web Security Solutions Integrating Web Security using ICAP Service Configuring ICAP Service, page 560 Configuring the proxy to communicate with ICAP Service Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x The precise steps required to configure the third-party proxy to communicate with Websense ICAP Service vary from product to product. For Blue Coat SG Series appliances running SGOS 6.2 or later: 1. Log on to the Management Console and go to Configuration > External Services > ICAP. 2. Create an ICAP Service with a name like “WebsenseICAP.” 3. Enter the Service URL in the following format: icap://<ICAP_server_address>/<service_name> For example: icap://10.100.57.120/icap See Configuring ICAP Service, page 560, for more information about setting or determining the service name. 4. Under ICAP Service Ports, verify that This service supports plain ICAP connections is selected, and that the Plain ICAP port value is set to 1344 (default). See Configuring ICAP Service, page 560, for information about changing the ICAP port. 5. Under ICAP v1.0 Options, click Sense settings to request settings from Websense ICAP Service. When the settings are retrieved, the Client address, Server address, and Authenticated user boxes should be marked, and “WEBSENSE” should appear as the ICAP server tag. If you do not want the proxy to authenticate users and pass user name information to Websense software as part of the ICAP request, deselect the Authenticated user check box. 6. Click OK to close the Edit window. Additional configuration steps include: Configure a Web Access Layer rule to pass all traffic from any source to any destination to the ICAP server configured above, and specify whether the proxy Deployment and Installation Center 559 Integrating Web Security using ICAP Service should fail open (permit all traffic) or fail closed (block all traffic) when the ICAP server is not available. Configure a Web Access Layer rule to allow all traffic to the IP address of the Websense Filtering Service machine. This allows client browsers to receive Websense block pages. If you want the proxy to authenticate users and pass user name information to Websense software, configure an authentication rule to authenticate users against a supported directory service. Note that if you are using Active Directory for user authentication, and use a hostname to identify the Active Directory server, make sure that the hostname resolves to the same IP address for both the third-party proxy and TRITON - Web Security. Also, if Active Directory is identified by hostname in the proxy, the hostname is what appears in log records, even if Active Directory is identified by IP address in TRITON - Web Security. Optionally configure HealthCheck for the external ICAP server. This causes the Blue Coat appliance to periodically send a URL filter request to the Websense ICAP Service to ensure that it is still running and responding correctly. Configuring ICAP Service Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x Websense ICAP Service behavior can be customized by modifying a configuration file called icap.conf, located in the Websense bin directory (C:\Program Files or Program Files (x86)\Websense\Web Security\bin, or /opt/Websense/bin/, by default) on the ICAP Service machine.

Deployment and Installation Center 561 Integrating Web Security using ICAP Service 562 Websense Web Security Solutions 24 Installing Web Security for Universal Integrations Deployment and Installation Center | Web Security Solutions | Version 7.7.x Applies to: Web Filter and Web Security, v7.7.x In this topic Installing Web Security for universal integrations, page 564 Migrating to a different integration after installation, page 564 This document describes integrating Websense Web Security solutions with supported integration products other than those addressed in the following topics: Integrating Web Security with Check Point, page 445 Integrating Web Security with Cisco, page 481 Integrating Web Security with Citrix, page 513 Integrating Web Security using ICAP Service, page 557 Integrating Web Security with Microsoft Products, page 535 Refer to the list of Websense Technology Partners (www.websense.com/global/en/ Partners/TAPartners/SecurityEcosystem/) to verify that Websense software supports an integration with your firewall, proxy server, caching application, or network appliance. Integrating Websense software with another product or device affects the following Websense components: Filtering Service interacts with your integration product and Network Agent to determine whether Internet requests are blocked or permitted. Network Agent manages Internet protocols that are not managed by your integration product. It can also detect HTTP network activity (managed by the integration) to enable bandwidth reporting. When the integration product receives an Internet request, it queries Websense Filtering Service to find out if the requested site should be blocked or permitted. Filtering Service consults the policy assigned to the client determines how the requested site is categorized. Deployment and Installation Center 563 Installing Web Security for Universal Integrations If the site is assigned to a blocked category, the client receives a block page instead of the requested site. If the site is assigned to a permitted category, Filtering Service notifies the integration product to grant access to the site. Installing Web Security for universal integrations This section provides a general overview of the installation process, highlighting the steps important to enabling integration. For detailed installation instructions, see Installing Web Security solutions, page 193. 1. When you install Filtering Service, on the Integration Option screen, select Integrated with another application or device. 2. On the Select Integration screen, select Other (Universal Integration). 3. On the Transparent User Identification screen you can choose whether to install a Websense transparent identification agent. If your integration product provides user authentication or identification services, or if you do not intend to use user and group-based filtering, select None. To use Websense software for user identification, select the agent or combination of agents appropriate for your deployment. 4. Follow the remaining installer prompts to complete the installation. After installation is complete: To prevent users from circumventing Websense filtering, configure your firewall or Internet router to allow outbound HTTP, HTTPS, FTP, and Gopher requests only from your integration product. Contact your router or firewall vendor for information about configuring access lists for that product. If Internet connectivity of Websense software requires authentication through a proxy server or firewall for HTTP traffic, the proxy server or firewall must be configured to accept clear text or basic authentication to enable the Websense Master Database download. Depending on the integration product you are using, you may also need to configure client computers to access the Internet through it to enable Websense filtering. Consult your integration product’s documentation to make this determination. Migrating to a different integration after installation You can change your integration product or version after installing Websense software without losing any of your configuration data. 564 Websense Web Security and Web Filter Installing Web Security for Universal Integrations 1. Install and configure your new integration product. See your integration product documentation for instructions. Ensure that it is deployed in your network such that it can communicate with Filtering Service and Policy Server. 2. Use the Websense Backup Utility to backup the Websense configuration and initialization files. See TRITON - Web Security Help for instructions 3. Ensure that Websense software is running. The installer looks for Policy Server during the installation process. 4. Remove Filtering Service using the procedures for removing components in the installation materials. Warning Remove Filtering Service only. Do not remove the associated Policy Server. If you have uninstalled Filtering Service from a Windows machine, restart the machine to complete the remove process. 5. Close any open applications, and stop any antivirus software, then run the Websense installer again. 6. Add Filtering Service using the procedures for installing individual components. See Adding Web Security components, page 690. 7. On the Integration Option screen, select Integrated with another application or device. 8. On the Select Integration screen, select Other (Universal Integration). 9. Follow the installer prompts to complete the installation. The installer adds the new integration data, while preserving the previous configuration data. On Windows machines, to complete the installation, restart the machine. 10. Verify that Filtering Service has started. Windows: Open the Services dialog box (Start > Programs > Administrative Tools > Services) and check to see if Websense Filtering Service is started. Linux: Navigate to the Websense installation directory (/opt/Websense, by default), and enter the following command to see if Websense Filtering Service is running: ./WebsenseAdmin status To start a service, follow the instructions in the installation materials. 11. To identify which Filtering Service instance is associated with each Network Agent: a. Log on to TRITON - Web Security and go to Settings > Network Agent. b. Highlight the General option, then select a Network Agent IP address to open its Local Settings page. Deployment and Installation Center 565 Installing Web Security for Universal Integrations c. Under Filtering Service Definition, select the IP address for the machine running Filtering Service. During the migration, the setting may have been reset to None.

You must configure your firewall to open the new ports before upgrading to v7.7. The new ports for communicating with the Data Security Management Server for data loss prevention are 17500-17515. Content Gateway, Email Security Gateway, and all Data Security components communicate with this server. The ports for communicating with Email Security Gateway have also changed. They are 17700-17714. You can reconfigure the base port after upgrade using the Modify wizard if desired. In addition: Tip When you follow a link in this list, right-click the link and open it in a new window or tab. This makes it easier to return to the outline and continue working through the prerequisites. Unless instructed otherwise by Websense Technical Support, ensure your system is functional prior to upgrade. Perform a full backup of your system before upgrading. See: Backing up TRITON infrastructure settings, page 588 Backing up Web Security configuration, page 587 How do I back up and restore Websense Content Gateway? Preparing the Web Security Log Database for upgrade, page 588 Back up appliance configuration and settings, page 619 How do I back up and restore Data Security software? If you are upgrading Data Security: Disable all network and endpoint discovery tasks as well as all fingerprinting tasks so that they don’t run during the upgrade process. Wait until there are no new endpoint discovery incidents appearing in the Data Security incidents report. Ensure that your supplemental fingerprint repositories are fully synchronized with the primary repository. Download the pre-upgrade tool dss_773_pre_upgrade_tool.zip from MyWebsense. This tool should be used for upgrades from 7.6.3 to 7.7.0 or 7.7.2, and for upgrades from 7.7.0 or 7.7.2 to 7.7.3. Place the file in any folder on the management server, extract and run it. It requires administrator permissions, so depending on your UAC settings you may be prompted to allow it to run as Administrator. When the tool has finished, a log file displays results. Deployment and Installation Center 569 Upgrading Websense Security Solutions to v7.7.x If the tool cannot connect to your SQL server, it saves 5 SQL files in the same folder as the tool—dss_sql_script_1.sql to dss_sql_script_5.sql. You can log onto the server and run the SQL portion of the tool manually by executing the files in order. If you are upgrading to Data Security v7.7.0, ensure that the user name and password set for the TRITON Unified Security Center account/Local Administrator account does not exceed 19 characters. Modify these settings if necessary. If you are upgrading it to v7.7.2 or beyond, this is not necessary. The TRITON upgrade process guides you through upgrading all components on the selected machine. You cannot choose which components to upgrade. Partial upgrades are not supported. When upgrading the TRITON management server, if upgrade fails for any component except TRITON Infrastructure, you can either continue to upgrade the rest of the components or exit the process and modify component settings. You cannot continue if the infrastructure upgrade fails. You cannot roll back a component that was upgraded successfully. After upgrade, your system has the same configuration as before the upgrade. The upgrade process does not allow you to change your configuration or settings. Also see: Web Security: Before upgrading Web Security to v7.7, page 582 Appliance: Preparing for the appliance upgrade, page 619 Upgrade sequence for solutions that include Web, Email, and Data Security Deployment and Installation Center | Web, Data, and Email Security Solutions | Version 7.7.x and earlier Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.6.7 and earlier Data Security, v7.7.x Email Security Gateway and Email Security Gateway Anywhere, v7.6.x If you have a mixed topology, upgrade components in the following order: 1. The machine hosting Web Security Policy Broker This may be a software (Windows or Linux) installation or the full policy source appliance. If Policy Broker is on an appliance, it does not matter whether the appliance is running in Web Security or Web and Email Security mode. 570 Websense Software Upgrades Upgrading Websense Security Solutions to v7.7.x If Policy Broker is on the same machine as other Web, Data, or Email Security components, still upgrade the Policy Broker machine first. After Policy Broker is upgraded, Content Gateway instances on other machines do not perform Web filtering until they are also upgraded. 2. Additional instances of Web Security Policy Server May be software-based or on user directory and filtering appliances. If Policy Server is on an appliance, it does not matter whether the appliance is running in Web Security or Web and Email Security mode. 3. Additional instances of Web Security Filtering Service or User Service Additional instances of Filtering Service may be software-based or on filtering only appliances. If Filtering Service is on an appliance, it does not matter whether the appliance is running in Web Security or Web and Email Security mode. 4. Web and Email Security Log Server If these components are on separate machines, it does not matter which is upgraded first. Important Make sure that no Email Security Log Database or Web Security Log Database jobs are running while the Log Server instances are being upgraded. 5. TRITON management server (includes TRITON infrastructure, as well as Web, Email, and Data Security management components) Whenever possible, upgrade the management server before any other Data Security components. This ensures that Data Security policy engines (and thus analysis) continue to function until they are upgraded themselves. Note that you cannot deploy new policies to the policy engines until they are upgraded to the same version as the management server. If you need to upgrade a Data Security policy engine before upgrading the TRITON management server—because the policy engine resides on a full policy source appliance—detection of fingerprinted content might not work on the appliance until the management server is upgraded. The Data Security policy engine embedded in Content Gateway and Email Security Gateway continues to monitor the old Web and email DLP policies and block/permit accordingly. 6. Any appliances running in Email Security mode The Email Security Gateway MTA continues to function after the management server upgrade, but the logs are cached on the appliance until Email Security Gateway is upgraded as well. For best practice, upgrade Email Security Gateway as soon as possible after the management server, or email traffic must be redirected to another MTA. If your appliances are running in Web and Email Security mode, all appliances may already have been upgraded in steps 1-3. Deployment and Installation Center 571 Upgrading Websense Security Solutions to v7.7.x 7. Other Web Security components (including software-based installations of Content Gateway) 8. Other Data Security components Important The components running on the machine you are upgrading go down until the upgrade is complete. You should plan for a brief period of down time. Upgrade procedure for solutions that include Web, Email, and Data Security This procedure covers the steps required to upgrade either the whole of Websense TRITON Enterprise or a Web and Email Security solution. (Note that Email Security Gateway and Gateway Anywhere always include Data Security components.) Tip When you follow a link this procedure, right-click the link and open it in a new window or tab.

To make the transition to ICAP integration, first upgrade to v7.7. • If you are moving from an on-box integration, next install v7.7 Filtering Service. Be sure to select the integrated option, and specify Websense ICAP Service as the integration product. Note that after upgrade, you must recreate your policies in TRITON Web Security, because you are now using Websense Filtering Service for policy enforcement. • If you are transitioning an off-box integration, uninstall Filtering Service, then reinstall it, selecting Websense ICAP Service as the integration product. Transitioning off-box integration with Blue Coat does not affect your existing policies. Deployment and Installation Center 583 Upgrading Websense Web Security Solutions See Integrating Web Security using ICAP Service, page 557, for more information about installing and configuring Websense ICAP Service. To review current integration requirements for other products, see Installing Web Security for Universal Integrations, page 563. 4. Back up all of your Websense components before starting the upgrade process. For Web Security software backup instructions, see Backing up Web Security configuration, page 587. For V-Series Appliance backup instructions, see Using the backup utility in Appliance Manager Help. For v7.6 TRITON settings, see Backing up TRITON infrastructure settings, page 588. 5. If you are upgrading from v7.5, there have been changes to the underlying structure of the management console (the TRITON Unified Security Center). See Placing the Web Security management console (v7.5 only), page 586, for help in determining whether you will need to move management components on upgrade. 6. If you are upgrading from v7.5, using delegated administration, and allow administrators to log on using their network accounts: Make sure that your directory service includes an email address for each user account defined as a Websense delegated administrator. Group accounts do not need to have an email address assigned in the directory. See Upgrading or merging administrator accounts, page 761, for more information. 7. Before upgrading Websense Filtering Service, make sure that the Filtering Service machine and the management server (TRITON - Web Security machine) have the same locale settings (language and character set). After the upgrade is complete, Filtering Service can be restarted with any locale settings. 8. It is important that you back up your current Log Database and stop any active SQL Server Agent jobs prior to upgrading. See Preparing the Web Security Log Database for upgrade, page 588. 9. If Websense Log Server uses a Windows trusted connection to access the Log Database, be sure to log on to the Log Server machine using the trusted account to perform the upgrade. To find out which account is used by Log Server: a. Launch the Windows Services dialog box (Start > Administrative Tools > Services). b. Scroll down to find Websense Log Server, then check the Log On As column to find the account to use. 10. If your deployment includes V-Series appliances, see Preparing for the appliance upgrade, page 619, for additional preparatory steps. 584 Websense Web Security Solutions Upgrading Websense Web Security Solutions Restart services before starting the upgrade Websense services must be running before the upgrade process begins. If any service is stopped, start it before initiating the upgrade. The installer will stop and start Websense services as part of the upgrade process. If the services have been running uninterrupted for several months, the installer may not be able to stop them before the upgrade process times out. To ensure the success of the upgrade, manually stop and start all the Websense services before beginning the upgrade. See Starting and stopping Web Security services, page 709, for instructions. On Windows machines, if you have configured the Recovery properties of any Websense service to restart the service on failure, use the Windows Services dialog box to change this setting to Take No Action before upgrading. Internet access during the upgrade process When you upgrade a standalone installation, filtering stops when Websense services are stopped. Users have unfiltered access to the Internet until the Websense services are restarted. If Websense Web Security solutions are integrated with another product or device, all traffic is either permitted or blocked during the upgrade, depending on how your integration product is configured to respond when Websense Filtering Service is unavailable. The Websense Master Database is removed during the upgrade process. Websense Filtering Service downloads a new Master Database after the upgrade is completed. Find your upgrade procedure When you are sure you have complete backups of your existing configuration and are ready to begin the upgrade process, see: Upgrading Web Filter or Web Security software-only deployments from v7.5.x, page 591 Upgrading Web Security or Web and Data Security solutions from v7.6, page 594 Deployment and Installation Center 585 Upgrading Websense Web Security Solutions Placing the Web Security management console (v7.5 only) Deployment and Installation Center | Web Security Solutions | Version 7.5.x Applies to: Web Filter and Web Security, v7.5.x This topic assumes that you have only Websense Web Filter or Web Security (not Web Security Gateway or Gateway Anywhere). If you have one of the Web Security Gateway solutions, you must upgrade to v7.6 before upgrading to v7.7. Version 7.7 includes a single management console for system configuration, policy management, and reporting for all Websense security solutions. The management console is called the TRITON Unified Security Center (often abbreviated to TRITON console). The Web Security module of the TRITON console is called TRITON - Web Security. All management components run on the same machine, called the TRITON management server. When upgrading from v7.5, you can upgrade your management console in place, if it is installed on a Windows Server 2008 32-bit machine or a Windows Server 2008 R2 machine. When you upgrade in place, a new component, TRITON Infrastructure, is installed first. This is the piece that ties together all management modules, and allows for centralized configuration of administrator accounts and other shared settings. Once TRITON Infrastructure is installed, the Web Security management console is upgraded. If your management components are on Linux, or on Windows 2003 or earlier, you must move management components to a different machine. If management components are on a Linux operating system supported for other Web Security components, you can remove the existing management components during upgrade of the machine (when prompted by the upgrade process), then later create a TRITON management server on a Windows machine. If management components are on an operating system that is not supported in v7.7, you can either: Migrate components to a supported operating system at your existing version, then upgrade to v7.7. See Migrating Web Security to a new operating system, page 661. 586 Websense Web Security Solutions Upgrading Websense Web Security Solutions If Policy Broker and Policy Broker are running on an operating system supported in v7.7, optionally uninstall management components before upgrade, perform the upgrade, then create a TRITON management server on a supported Windows machine. See Creating a TRITON Management Server, page 180. Backing up Web Security configuration Deployment and Installation Center | Web Security Solutions | Version v7.0.x - v7.6.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.0.x - v7.6.x Before upgrading to a new version of Websense Web Security components, it is a best practice to perform a full system backup. This makes it possible to restore the current production system with minimum downtime, if necessary. Use the Websense Backup Utility on each non-appliance machine that contains Websense Web Security components: 1. Stop Websense services. See Starting and stopping Web Security services, page 709. 2. Do one of the following: Windows: Open a command prompt (Run > cmd) and navigate to the Websense bin directory. The default location is: v7.0 - v7.5: C:\Program Files\Websense\bin v7.6: C:\Program Files or Program Files (x86)\Websense\Web Security\bin Linux: Navigate to the Websense installation directory (/opt/Websense, by default). 3. Use the following command to run the Backup Utility: Windows: wsbackup -b -d <directory> Linux: ./WebsenseTools -b -b -d <directory> For these commands, <directory> is the path where the backup file will be stored. The Backup Utility saves the essential Websense software files on the machine on which it is run, including any custom block pages. A complete list of the files saved can be found in the TRITON - Web Security Help for your version. (For v7.6, the list is also included in the Backup and Restore FAQ.) Deployment and Installation Center 587 Upgrading Websense Web Security Solutions Repeat this process on all machines on which Websense Web Security components are installed, and make sure that the files are stored in a safe and accessible location. 4. Start the Websense services. The Websense services must be running when you start the upgrade. If you are upgrading from v7.6, also back up your TRITON Infrastructure settings. See Backing up TRITON infrastructure settings, page 588. Backing up TRITON infrastructure settings Deployment and Installation Center | Web Security Solutions | Version 7.6.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.6.x If you are running v7.6, also use the TRITON backup utility to back up your TRITON Settings information (administrator accounts, for example). 1. On the TRITON management server machine, do one of the following: Windows Server 2008 or 2008 R2: Go to Start > Administrative Tools > Task Scheduler, then select Task Scheduler Library. Windows Server 2003: Go to Start > Control Panel and select Scheduled Tasks. 2. If the Triton Backup task is disabled, right-click the task and select Enable. 3. Right-click the Triton Backup task and select Run. Preparing the Web Security Log Database for upgrade Deployment and Installation Center | Web Security Solutions | Version 7.0.x - v7.6.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.0.x - v7.6.x 588 Websense Web Security Solutions Upgrading Websense Web Security Solutions It is important that you back up your current Websense reporting databases and stop any active SQL Server Agent jobs prior to upgrading. After upgrade, reactivate the jobs to resume normal database operations. Warning If database operations are active during upgrade, the Websense Log Database may be left in an inconsistent state, rendering it unusable. When this occurs, it can be difficult to fix. Make sure to stop Log Server and the database jobs, as described below, before upgrading the database. 1. Back up Web Security reporting databases. Refer to Microsoft documentation for instructions on backing up databases. The Websense Web Security databases are named wslogdb70 (the catalog database) and wslogdb70_1, wslogdb70_2, and so on (partition databases). 2. On the Log Server machine, use the Windows Services dialog box (Start > Administrative Tools > Services) to stop Websense Log Server. 3. Log in to the Microsoft SQL Server Management Studio and expand SQL Server Agent > Jobs (in Object Explorer). 4. To disable all currently active Websense SQL Server Agent jobs, right-click each of the following jobs and select Disable: Websense_ETL_Job_wslogdb70 Websense_IBT_DRIVER_wslogdb70 Websense_Mantenance_Job_wslogdb70 Disabling the jobs prevents them from executing at the next scheduled time, but does not stop them if a job is in process. Make sure all jobs have completed any current operation before proceeding with upgrade. 5. Perform the Websense upgrade. 6. After upgrade, enable the disabled jobs to resume normal database operations. Web Security upgrade order Deployment and Installation Center | Web Security Solutions | Version 7.0.x - v7.6.x Applies to: Web Filter, Web Security, Web Security Gateway, and Web Security Gateway Anywhere, v7.0.x - v7.6.x Deployment and Installation Center 589 Upgrading Websense Web Security Solutions When you upgrade Websense Web Security solutions, the installer or appliance patch automatically upgrades all components on a given machine in the correct order. As a result, if you have a main server or appliance hosting most of your Web Security components (including Policy Broker), upgrade that machine first, then use the list below to determine the upgrade order for any additional servers or appliances. If your components are widely distributed, however, ensure that they are upgraded in the correct order, as follows: 1. Policy Broker If you are using Websense V-Series appliances, Policy Broker runs on the full policy source appliance or server. Regardless of the other components running on the machine, always upgrade the Policy Broker machine first. The other components on the machine are upgraded in the correct order. 2. Policy Server Runs on all user directory and filtering appliances, and may run on other Windows or Linux servers. 3. User Service, Filtering Service, and Directory Agent This includes all filtering only appliances, and may include other Windows or Linux servers. 4. Log Server and Sync Service Make sure that all Log Database jobs are stopped before starting the Log Server upgrade. See Preparing the Web Security Log Database for upgrade, page 588. 5. Websense Manager or TRITON - Web Security 6. Network Agent, Content Gateway 7. Transparent identification agents, Remote Filtering Server, Filtering plug-in (Citrix XenApp or Microsoft Forefront TMG) Important The Web Security server components must be all be upgraded to the same version. They are not cross-version compatible with one another. Once all server components have been upgraded, upgrade client components (the logon application, Remote Filtering Client, Web Endpoint) in any order.

Deployment and Installation Center 609 Upgrading Content Gateway to v7.7.x Upgrading Content Gateway on a V-Series appliance is handled by the V-Series upgrade (patch) process. See Upgrading V-Series Appliances to v7.7. Before you begin, be sure to read Preparing to install Websense Content Gateway. Warning Before you begin, ensure that /tmp has enough free space to hold the existing Content Gateway log files. During the upgrade procedure, the installer temporarily copies log files located in /opt/WCG/logs to /tmp. If the /tmp partition does not have enough available space and becomes full, the upgrade will fail. If you determine that /tmp does not have enough space, manually move the contents of /opt/WCG/logs to a partition that has enough space and then delete the log files in /opt/WCG/logs. Run the installer to perform the upgrade. When the upgrade is complete, move the log files from the temporary location back to /opt/WCG/logs and delete the files in the temporary location. For step-by-step instructions, see the Knowledge Base article titled Upgrading can fail if the /tmp partition becomes full. Note: /opt/WCG is the version 7.6 installation location. 1. Acquire root permissions: su root 2. If you are upgrading from versions 7.6.0 only: If configured, disable clustering and leave disabled until all members of the cluster are upgraded. If configured, disable Virtual IP failover and leave it disabled until all members of the cluster are upgraded and re-enabled. 3. Disable any currently running firewall on this machine for the duration of the Content Gateway upgrade. Bring the firewall back up after upgrade is complete, opening ports used by Content Gateway. For example, if you are running IPTables: a. At a command prompt, enter service iptables status to determine if the firewall is running. b. If the firewall is running, enter service iptables stop. c. After upgrade, restart the firewall. In the firewall, be sure to open the ports used by Content Gateway on this machine. See Websense TRITON Enterprise default ports for more information. 4. Download the Content Gateway version 7.7.x installer from mywebsense.com and save it to a temporary directory. For example: 610 Websense Web Security Gateway Solutions Upgrading Content Gateway to v7.7.x mkdir wcg_v77 mv <installer tar archive> wcg_v77 5. Unpack the Content Gateway installer tar archive: cd wcg_v77 tar -xvzf <installer tar archive> Important If SELinux is enabled, set it to permissive, or disable it before installing Content Gateway. Do not install or run Content Gateway with SELinux enabled. 6. In the directory where you unpacked the tar archive, start the installation/upgrade script. ./wcg_install.sh Respond to the prompts. Content Gateway is installed and runs as root. Note Up to the point that you are prompted to confirm your intent to upgrade, you can quit the installer by pressing CTRL+C. If you change your mind after you choose to continue, do not use CTRL+C to stop the process. Instead, allow the installation to complete and then uninstall it. 7. If your system does not meet the minimum recommended requirements, you receive a warning. For example: Warning: Websense Content Gateway requires at least 2 gigabytes of RAM. Do you wish to continue [y/n]? Enter n to quit the installer, and return to the system prompt. Enter y to continue the upgrade. If you choose to run Content Gateway after receiving this warning, performance may be affected. 8. Read the subscription agreement. At the following prompt, enter y to accept the agreement and continue the upgrade, or n to cancel. Do you accept the above agreement [y/n]? y 9. When asked, choose to replace the existing version of Content Gateway with the 7.7.x version. WCG version 7.6.n-nnnn was found. Do you want to replace it with version 7.7.x-nnnn [y/n]? y 10. Existing settings and logs are copied to backup files and stored. For example: Stopping Websense Content Gateway processes...done Copying settings from /opt/WCG to /root/WCG/OldVersions/ 7.6.0-1143-20110322-131541/...done Deployment and Installation Center 611 Upgrading Content Gateway to v7.7.x Copying SSL Manager settings to /root/WCG/OldVersions/ 7.6.0-1143-20110322-131541/...done Moving log files from /opt/WCG/logs to /tmp/wcg_tmp/logs/ ...done 11. You can either re-use the installation selections you entered during the last install, or provide new answers to all installation prompts: Previous install configuration </root/WCG/Current/ WCGinstall.cfg> found. Use current installation selections [y/n]? Enter y to use previous installation selections. Enter n to revert to Websense default values, and receive all installation questions and answer them again. 12. If you answered y at Step 11, then you can also leave proxy settings at their current values or revert to Websense default values. Restore settings after install [y/n]? Enter y to keep the proxy settings as they are. Enter n to restore Websense default settings for the proxy. 13. If you answered n at Step 11, the current version of Websense Content Gateway is removed, and a fresh install of 7.7.x begins. See Installing Websense Content Gateway for a detailed description of the installation procedure. 14. The previously installed version of Websense Content Gateway is removed, and the settings and selections you chose to retain are re-used. Wait. *COMPLETED* Websense Content Gateway 7.7.0-1200 installation. A log file of this installation process has been written to /root/WCG/Current/WCGinstall.log For full operating information, see the Websense Content Gateway Help system. Follow these steps to start the Websense Content Gateway management interface (Content Gateway Manager): -----------------------------------------------------------1. Start a browser. 2. Enter the IP address of the Websense Content Gateway server, followed by a colon and the management interface port (8081 for this installation). For example: https:// 11.222.33.44:8081. 3. Log on using username admin and the password you chose earlier. A copy of the CA public key used by the Manager is located in /root/WCG/. 15. The upgrade is now complete, and the proxy software is running. If you chose to revert to Websense default proxy settings, be sure to configure any custom options. 16. Check Content Gateway status with: 612 Websense Web Security Gateway Solutions Upgrading Content Gateway to v7.7.x /opt/WCG/WCGAdmin status All services should be running. These include: Content Cop Websense Content Gateway Content Gateway Manager Analytics Server Important If Content Gateway fails to complete startup after upgrade, check for the presence of the no_cop file. Look for: /opt/WCG/config/internal/no_cop If the file exists, remove it and start Content Gateway: /opt/WCG/WCGAdmin start 17. Refresh the browser cache when logging in to Content Gateway Manager for the first time after upgrade by pressing Shift+F5. The Content Gateway Manager user interface has an updated look and feel for version 7.7 and the old .css files may need to be flushed from your browser cache. 18. Perform the post-installation steps described in Post-upgrade activities and in Initial Configuration for All Websense Modules. Post-upgrade activities In version 7.7.x, when using Content Gateway with TRITON - Web Security, it is not necessary to enter a subscription key. The key is automatically fetched from TRITON - Web Security. 1. If at the start of the upgrade process you manually moved your existing log files to a temporary location, move them back to /opt/WCG/logs and delete the files in the temporary location. 2. Register Content Gateway nodes in TRITON - Web Security on the Settings > Content Gateway Access page. Registered nodes add a link to the Content Gateway Manager logon portal and provide a visual system health indicator, a green check mark or a red X icon. 3. Configure Content Gateway system alerts in TRITON - Web Security. Select Content Gateway system alerts are now sent to TRITON - Web Security (in addition to Content Gateway Manager). To configure which alerts are sent, in TRITON - Web Security go to the Settings > Alerts > System page. 4. If you were using Integrated Windows Authentication (IWA), re-enable it and join Content Gateway to the Windows Domain. Configure IWA using the settings you recorded prior to upgrade. See Configuring Integrated Windows Authentication in Content Gateway Manager Help. Deployment and Installation Center 613 Upgrading Content Gateway to v7.7.x 5. If you upgraded from version 7.6.0 and disabled clustering at the start of the upgrade process, re-enable clustering after all members of the cluster are upgraded and restart Content Gateway (restarting any node causes all nodes to restart). 6. If you upgraded from version 7.6.0 and disabled Virtual IP failover at the start of the upgrade process, re-enable Virtual IP failover after all members of the cluster are upgraded and clustering has been re-enabled. 7. If Web Security Gateway Anywhere and Data Security are deployed together and upgraded to version 7.7, you must remove stale entries of Content Gateway instances registered in Data Security system modules. From the TRITON Console, go to Data Security > Settings > Deployment > System Modules and delete instances that display an old version number. 8. If Web Security Gateway Anywhere and Data Security are deployed together and configured to use the on-box policy engine, and then reconfigured during upgrade or later to use the ICAP interface, the Content Gateway instance must be deleted from the list of Data Security system modules or the deployment will fail. Go to the Data Security > Settings > Deployment > System Modules page, click on the affected Content Gateway instance to open its Details page, click Delete and then Deploy. 9. Complete support for GRE Return Method with WCCP is added in version 7.7. If WCCP with GRE is already configured, the existing configuration continues to function as it did in v7.6.x. Note that Content Gateway Manager will produce an alarm suggesting that you update your configuration. Updating the configuration migrates the configuration to the new GRE support infrastructure. You do not have to change your configuration unless you want to add the GRE Return Method. Important If you are using WCCP with Cisco ASA, after the upgrade your configuration continues to perform as it did with v7.6.x. There is no need to change your configuration after upgrade. In version 7.7.0, should you need to reconfigure Content Gateway to work with your ASA device, set the Forward and Return Method to L2. This forces Content Gateway to negotiate the correct supported method. In version 7.7.3, should you need to reconfigure Content Gateway to work with your ASA device, access the Service group settings and select ASA Firewall from the Special Device Profile drop down box instead of individually selecting the GRE forward and return methods. This automatically selects the Packet Forward Method and Packet Return Method and sets some proxy internals. 614 Websense Web Security Gateway Solutions Upgrading Content Gateway to v7.7.x 10. If you use SSL Manager to process HTTPS traffic, the Root CA should be imported into all affected clients. In v7.7 (and beginning with v7.6.5), the Content Gateway default Root CA presented to clients is signed with SHA-1. In prior versions, the Root CA was signed with MD5. It is strongly recommended that all instances of Content Gateway use the same Root CA, and that for best security the signature algorithm be SHA-1. Note Client connections may fail (depending on specific browser behavior) if the client sees a certificate generated by an unknown Root CA. The best practice is to replace the Websense default Root CA with your organization’s Root CA signed by SHA-1 or stronger. See Internal Root CA in Content Gateway Help.

When the backup file appears in the Local Backup Files list, click the backup file name. When prompted, save the backup file in another location. Content Gateway logs If the appliance hosts Web Security Gateway (Anywhere), during the upgrade, depending on their size, older Content Gateway logs may be automatically removed by the upgrade procedure. To ensure that all Content Gateway logs are retained, you can download the Content Gateway logging directory. 1. In the Appliance Manager, go to Administration >Logs. 2. Select the Websense Content Gateway module and then Download entire log file. 3. Click Submit and specify a location to save the file. Policy databases and Websense databases are not affected by the upgrade. Content Gateway Integrated Windows Authentication (IWA) settings IWA settings are not preserved in the upgrade. If your deployment uses Content Gateway IWA user authentication, log onto Content Gateway and record the IWA settings, including the name of the domain to which IWA is joined. Keep this record where you can easily retrieve it after upgrade is complete. Network Agent settings In the majority of deployments, upgrade preserves all Network Agent settings. However, when the following conditions are true, the upgrade process does not preserve several Network Agent settings: There is a Filtering only appliance that is configured to get policy information from the Policy Broker machine (either the Full policy source appliance or an off-appliance software installation). There is an off-appliance Network Agent installation that uses the Filtering Service on the Filtering only appliance, and uses the Policy Server on the Policy Broker machine. When the above conditions are true and the upgrade is performed, the settings for the off-appliance Network Agent installation are not retained. In this case, record your Network Agent settings (configured in TRITON - Web Security) before performing the upgrade. Go to the Local Settings page for each Network Agent instance (Settings > Network Agent > agent_IP_address) and record all of its settings. The following local settings are not preserved. Filtering Service IP address 620 Websense V-Series Appliances Upgrading V-Series Appliances to v7.7 If Filtering Service is unavailable Proxies and Caches Port Monitoring Ignore Port Debug Setting NIC Configuration settings (from the Settings > Network Agent > NIC Configuration page for each NIC) are also not preserved: Use this NIC to monitor traffic Monitor List Monitor List Exceptions Save your record where you can easily access it when the upgrade is complete.

Use this link if you want to create a backup of TRITON settings that can be restored to the off-appliance TRITON Unified Security Center: a. Click the backup file link that is displayed below the Disabled button. b. If a certificate error is displayed, click the continue or accept option to start the download. c. Save the TRITON backup file (EIP_bak.tgz) in a convenient location. Upgrade instructions Important V-Series appliance services are not available while the patch is being applied and until the appliance completes its restart. See Estimates of time to complete upgrade, page 618. It is best to perform the upgrade at a time when service demand is low. 1. If you have multiple V-Series appliances, read Upgrading multiple V-Series appliances, page 623, before following this procedure. 2. Take all precautions to ensure that power to the V-Series appliance is not interrupted during the upgrade. Power failure can result in operating system and software component corruption. 3. Back up appliance configuration and settings. See Back up appliance configuration and settings, page 619. 4. Restart the appliance (in Appliance Manager: Status > Modules > Restart Appliance). 5. To download the upgrade patch, in the Appliance Manager, go to the Administration > Patches/Hotfixes > Patches tab. The 7.7.x upgrade patch should be listed in the Table of available patches. If it’s not, click Check for Patches. The 7.7 patch should be listed as available. Alternatively, the patch can be downloaded from websense.com and uploaded to the appliance. a. Go to MyWebsense.com and select the Downloads tab. Click Get Hotfixes & Patches. Select your appliance model and version. b. Log on to the Appliance Manager and navigate to Administration > Patch Management. 622 Websense V-Series Appliances Upgrading V-Series Appliances to v7.7 c. Click Browse, and select the v7.7.x upgrade file. d. Click Upload. After a few seconds, the upgrade is listed in the Uploaded patches list. This is an efficient method when your deployment has many appliances because the download from Websense occurs only once. Other appliances can upload the patch from the local location. 6. Click Install to apply the upgrade. Important When patch installation begins, a dialog box indicates that the patch will take 5 to 10 minutes to apply. This is incorrect. The time is significantly longer. See Estimates of time to complete upgrade, page 618. While the upgrade is being applied, services are unavailable to users. 7. When patch installation is complete, restart the appliance right away; click Restart Now when prompted. Do not cycle the power. 8. When the appliance has restarted, log on to the Appliance Manager and verify on the Configuration > General page that the V-Series version is 7.7.x. Next go to the System > Configuration page and confirm and adjust, if necessary, the Time and Date settings, paying particular attention to the time zone setting. In rare cases, when logging onto the Appliance Manager for the first time after upgrade, your browser may show an HTTP Status - Internal Error page. If this occurs, cycle the power to the appliance. Once the appliance has restarted, you should be able to log in. 9. If you have multiple appliances, upgrade them all. See Upgrading multiple V-Series appliances. 10. Upgrade all Websense components running off the appliance (including the TRITON management server, Web and Email Security Log Server, transparent identification agents, and so on). See Upgrading Websense Web Security Solutions, page 579, and Upgrading Email Security Gateway to v7.7, page 669, for instructions. Upgrading multiple V-Series appliances When multiple V-Series appliances are deployed in the same network, it is very important that they be upgraded in the prescribed order. If the appliance is an Email mode (only) appliance Apply the 7.7.x upgrade patch before upgrading the off-appliance components. Best practice for upgrade sequence if Full policy source is on V-Series Deployment and Installation Center 623 Upgrading V-Series Appliances to v7.7 appliance Follow this sequence whether the Full policy source is a Web mode (only) or Web and Email mode appliance. Upgrade the Full policy source V-Series appliance and immediately restart when the upgrade completes. 1. Sequentially apply the upgrade to all User directory and filtering appliances. Restart each appliance when the upgrade completes. 2. Sequentially apply the upgrade to all Filtering only appliances. 3. Restart each appliance when the upgrade completes. 4. After all appliances have been upgraded, upgrade off-box components. Best practice for upgrade sequence if Full policy source is not on V-Series appliance If you have multiple V-Series appliances and the policy source (Policy Broker and Policy Server) is located off-appliance: 1. Use the version 7.7 Websense installer to upgrade the Policy Broker system. See Upgrading Websense Web Security Solutions, page 579, for instructions. 2. Sequentially apply the upgrade to all User directory and filtering appliances. Restart each appliance when the upgrade completes. 3. Sequentially apply the upgrade to all Filtering only appliances. 4. Use the version 7.7.x Websense installer to upgrade remaining off-appliance components. See Upgrading Websense Web Security Solutions, page 579, for instructions. If the Full policy source appliance is down or unavailable Best practice is to upgrade the Full policy source appliance first, then the User directory and filtering, then Filtering only appliances, and finally the off-appliance Websense components. However, if your site must upgrade a User directory and filtering or Filtering only appliance before the Full policy source appliance, or if your Full policy source appliance is unavailable, is being replaced, or is being re-imaged, then set a User directory and filtering or Filtering only appliance (temporarily) to be the Full policy source. To do this: 1. On that secondary appliance, in the V-Series console, navigate to Configuration > Web Security Components. 2. For Policy Source, select Full policy source. Save the setting. 3. Upgrade this appliance to version 7.7.x and restart it. After the original Full policy source appliance has been upgraded, replaced, or re-imaged, change the upgraded temporary Full policy source machine to point to the original Full policy source again for its policy information. To do this: 624 Websense V-Series Appliances Upgrading V-Series Appliances to v7.7 1. Upgrade the primary appliance and restart it. 2. On the previously upgraded secondary appliance, in the V-Series console, navigate to Configuration > Web Security Components. 3. For Policy Source, select User directory and filtering or Filtering only and enter the IP address of the primary appliance. Save the setting. 4. Use the version 7.7.x Websense installer to upgrade remaining off-appliance components. See Upgrading Websense Web Security Solutions, page 579, for instructions. Post-upgrade activities If your appliance includes Email Security Gateway (Anywhere), perform the Email Security Gateway Post-upgrade activities, page 673. If your appliance is a Web Security Policy Server, log onto TRITON console, go to the TRITON - Web Security Settings > General > Policy Servers page and add the appliance. Next go to the TRITON console Appliances tab and register the appliance. If your appliance includes Web Security Gateway (Anywhere), perform the Content Gateway Post-upgrade activities. If your appliance uses the Network Agent module, Verify Network Agent settings. Review the Release Notes for the Websense solutions on your appliances (links provided below). There are several new features that may require some configuration to put into effect. Web Security users will be especially interested in the Threats dashboard (no configuration needed). Web Security Gateway (Anywhere) users will be interested in the enhanced outbound scanning options. It is recommended that all of the Scanning Options be reviewed. Web Security Release Notes Content Gateway Release Notes Email Security Gateway Release Notes Verify Network Agent settings If you had to record your Network Agent settings prior to upgrade (Network Agent settings), restore them after the TRITON console has been upgraded. Log on to TRITON - Web Security and go to Settings > Network Agent > Local Settings. Select the IP address of the affected Network Agent installations and check and restore all values, paying particular attention to: Filtering Service IP address If Filtering Service is unavailable Proxies and Caches Port Monitoring Deployment and Installation Center 625 Upgrading V-Series Appliances to v7.7 Ignore Port Debug Setting Also, check the Settings > Network Agent > NIC Configuration page for each NIC: Use this NIC to monitor traffic Monitor List Monitor List Exceptions When your changes are complete, click OK and then Save and Deploy. 626 Websense V-Series Appliances 29 Upgrading Data Security to v7.7.x Deployment and Installation Center | Data Security Solutions | Version 7.7.x You can upgrade to Websense Data Security v7.7.3 directly from v7.7.0 or v7.7.2. If you have an earlier version, however, there are interim steps to perform. These are shown in the table below. Your current version Step 1 Step 2 Step 3 7.1.x Migrate to 7.6.0 Upgrade to 7.7.2 Upgrade to 7.7.3 7.5.x Upgrade to 7.6.0 Upgrade to 7.7.2 Upgrade to 7.7.3 7.6.x Upgrade to 7.7.2 Upgrade to 7.7.3 none 7.7.0 Upgrade to 7.7.3 none none 7.7.2 Upgrade to 7.7.3 none none For instructions on upgrading to any 7.7.x version, see the following topics: Upgrading the Data Security Management Server, page 628 Upgrading supplemental Data Security servers or standalone agents, page 629 Upgrading a Data Security protector or mobile agent, page 630 Upgrading Data Security endpoints, page 631 For instructions on upgrading to v7.6.0, see: Upgrading Data Security to v7.6.0, page 633 Deployment and Installation Center 627 Upgrading Data Security to v7.7.x Upgrading the Data Security Management Server Deployment and Installation Center | Data Security Solutions | Version 7.7.x To upgrade your management server, launch the latest TRITON installation package, WebsenseTRITON77xSetup.exe, where x is the version number. This is the same executable used for scratch installations. Important The ports for Data Security modules including Web Content Gateway have been consolidated to 17500-17515. The ports for communicating with Email Security Gateway have been consolidated to 17700-17714. Configure your firewall to open these ports before proceeding. The installation package detects that earlier versions of the product are installed, and automatically starts a series of upgrade wizards—one for each of the installed components. TRITON infrastructure Web Security Data Security Email Security The Data Security portion of the unified upgrade wizard upgrades all necessary components on the Data Security Management Server. See Upgrading the TRITON management server, page 574 for complete instructions on using the upgrade wizard. This section describes important steps to take before you begin the upgrade and after the upgrade is complete. Before upgrading: Disable all network and endpoint discovery tasks as well as all fingerprinting tasks so that they don’t run during the upgrade process. Wait until there are no new endpoint discovery incidents appearing in the Data Security incidents report. Ensure that your supplemental fingerprint repositories are fully synchronized with the primary repository. Download the pre-upgrade tool dss_773_pre_upgrade_tool.zip from MyWebsense. This tool should be used for upgrades from 7.6.3 to 7.7.0 or 7.7.2, and for upgrades from 7.7.0 or 7.7.2 to 7.7.3. Place the file in any folder on the management server, extract and run it. It requires administrator permissions, so depending on your UAC settings you may be prompted to allow it to run as Administrator. When the tool has finished, a log file displays results. 628 Websense Data Security Solutions Upgrading Data Security to v7.7.x If the tool cannot connect to your SQL server, it saves 5 SQL files in the same folder as the tool—dss_sql_script_1.sql to dss_sql_script_5.sql. You can log onto the server and run the SQL portion of the tool manually by executing the files in order. If you are upgrading to Data Security v7.7.0, ensure that the user name and password set for the TRITON Unified Security Center account/Local Administrator account does not exceed 19 characters. Modify these settings if necessary. If you are upgrading it to v7.7.2 or beyond, this is not necessary. Upgrading supplemental Data Security servers or standalone agents Deployment and Installation Center | Data Security Solutions | Version 7.7.x Complete these steps to upgrade a supplemental Data Security server or stand-alone agent (e.g. SMTP, printer, crawler, or ISA/TMG) to v7.7.x. See Upgrading Data Security to v7.7.x, page 627 to see if you can upgrade directly from your version or if you must perform interim upgrade steps. 1. Upgrade the Data Security Management Server. (See Upgrading the Data Security Management Server, page 628 for instructions.) This sequence is critical, because if you upgrade supplemental servers or agents first, they stop communicating with the management server. If you upgrade the management server first, it continues communicating with the components until they are upgraded. 2. If you are upgrading a supplemental server or stand-alone crawler or printer agent to v7.7.0, ensure that the user name and password set for the Local Administrator account does not exceed 19 characters. Modify these settings if necessary. This is not necessary if you are upgrading to v7.7.2 or beyond. 3. Download and run the upgrade installer, WebsenseTRITON77xSetup.exe, where x is the version number. 4. The installation wizard appears. 5. Click Next until you complete the wizard. Any v7.7.x Data Security components found on this machine are upgraded. 6. After the upgrade has successfully completed, deploy the agents or supplemental servers by logging on to TRITON- Data Security and clicking Deploy. 7. It is strongly recommended you wait 30 minutes before routing traffic though the upgraded system. When you upgrade a Data Security server it takes time for it to download the information necessary for resolving source and destination resources such as people, computers, and printers. Routing traffic through the system before this is complete may result in: Potential false positives and negatives. Deployment and Installation Center 629 Upgrading Data Security to v7.7.x File-system discovery starts but immediately indicates "completed with errors". Upgrading a Data Security protector or mobile agent Deployment and Installation Center | Data Security Solutions | Version 7.7.x Do the following to upgrade your protector or mobile agent from version to v7.7.x. See Upgrading Data Security to v7.7.x, page 627 to see if you can upgrade directly from your version or if you must perform interim upgrade steps. Important If you are upgrading your protector to new hardware, be sure to keep the original IP address/host name if you want to retain settings and information from the original machine. If you assign a new IP, the protector’s settings are cleared to default when it registers with the management server. In this case, you should manually delete the protector with the original IP address from the system modules page of TRITON - Data Security. 1. Upgrade the TRITON management server as described above. This sequence is critical, because if you upgrade the protector or mobile agent first, it stops communicating with the management server. If you upgrade the management server first, it continues communicating with the components until they are upgraded. 2. Copy the file, protector-update-7.7.x-yyyy, into the directory /tmp where x-yyyy is the latest version and build number. 3. Enter the command: chmod +x /tmp/protector-update-7.7.x-yyyy 4. If you are upgrading to v7.7.0 from v7.6.8, log on as root and run the following command: rm -r /var/tmp/yum_update_cache 5. Run the following command: bash ./tmp/protector-update-7.7.x-yyyy 6. Answer Y on the "Are you sure?" question, and complete the wizard, accepting the defaults. 7. Restart the protector or mobile agent machine when the wizard completes. 8. If you have not already, log onto the machine as root. 630 Websense Data Security Solutions Upgrading Data Security to v7.7.x 9. Run the following command to re-register the protector or mobile agent with the management server, then follow the prompts in the wizard: wizard securecomm 10. If you are upgrading to v7.7.0 from v7.6.8, run the following command: rm -r /var/tmp/yum_update_cache 11. In TRITON - Data Security, click Deploy. 12. It is strongly recommended you wait 30 minutes before routing traffic though the upgraded system. When you upgrade a protector, it takes time for it to download the information necessary for resolving source and destination resources such as people, computers, and printers. Routing traffic through the system before this is complete may result in false positives and negatives. Upgrading Data Security endpoints Deployment and Installation Center | Data Security Solutions | Version 7.7.x Before upgrading endpoint clients, do the following: 1. Upgrade the Data Security Management Server and any supplemental Data Security servers. 2. Disable all discovery tasks so that they don’t run during the upgrade process. 3. Wait until there are no new endpoint discovery incidents appearing in the Data Security incidents report. You can install endpoint packages on top of earlier versions without uninstalling and re-installing them. Windows After you have updated the Data Security Management Server: 1. Go to the %DSS_Home% directory (by default: c:\Program Files\Websense\Data Security\client\) and run WebsenseEndpointPackageBuilder.exe to create a new endpoint client package. 2. Choose Windows 32- or 64-bit when prompted. 3. Deploy the v7.7.x package to each endpoint using GPO, SMS, or a similar deployment method. You can install v7.7.x on top of earlier versions without uninstalling and re-installing them. 4. Restart the endpoint after installation is complete. Linux After you have updated the Data Security Management Server: Deployment and Installation Center 631 Upgrading Data Security to v7.7.x 1. Go to the %DSS_Home% directory (by default: c:\Program Files\Websense\Data Security\client\) and run WebsenseEndpointPackageBuilder.exe to create a new endpoint client package. 2. Choose Linux when prompted. 3. To upgrade Data Endpoint software on a Linux computer, copy the correct installer to the machine and run it as root. LinuxEndpoint_SFX_installer_el4 - should be used with Red Hat Enterprise Linux version 4.x. LinuxEndpoint_SFX_installer_el5 - should be used with Red Hat Enterprise Linux version 5.x. No reboot is necessary. The endpoint software starts automatically. You can install v7.7.x on top of earlier versions without uninstalling and re-installing them. See Deploying Websense endpoints, page 424 for more information. 632 Websense Data Security Solutions 30 Upgrading Data Security to v7.6.0 Deployment and Installation Center | Data Security Solutions | Version 7.7.x Applies to: Data Security, v7.1.x, 7.5.x, 7.6.x In this topic: General exceptions, page 633 v7.1 exceptions, page 633 v7.5 exceptions, page 634 Websense Data Security v7.1 and v7.5 can be upgraded to Data Security 7.6
